Reddit mentions: The best analitycal reagents

No problem. Yes I would imagine modified citrus pectin is far superior to IP-6. IP-6 is like tannic acid from acorns, it's other name is phytic acid, it's a weak acid chelator like vitamin C, malic acid and so on. It may help but it's not going to do the job by itself. If you wanted something other than edta and modified citrus pectin and garlic then I'd go with vitamin C and try and go with a higher dose, preferably something buffered like sodium ascorbate and 4+ grams at least twice a day but 3 would be best. Or if money isn't an issue vitality C, it's probably the best form of vitamin C on the market, can take higher doses without bowel upset, higher absorption and utilization than liposomal even, keeps blood levels high for 10 hours, liposomal is around 4 and plain sodium ascorbate is around 3. So with vitality C you keep blood levels high easily for 24 hours a day just taking it morning and night, dissolves very well and doesn't taste like salty water like sodium ascorbate but is slightly sweet. Very good product if you can afford it. Succinic acid is also another option after vitamin C and over IP-6, it's also a chelator but like vitamin C has a huge host of benefits, largely it is involved with energy production in the body and does many of things COQ10 does and more. The body already makes it. It's also quite cheap. It's also amazing for plant growth/health along with GABA.This is the one I use, it's food grade. I fill 00 capsules and take 1-2 a day. So a person could just take a quarter teaspoon of the powder which is around a gram. Can do less or more. It's like citric acid, slightly sour.
Haven't looked into ketogenic diet sorry no clue. Yes IR sauna is highly very effective and worth getting you can get pop up IR saunas to sit in for around 150 USD on amazon. I've had one that is still going strong for around 4 years now. I try to do it at least once a week. It usually takes around a hour and a half for what I do. So I watch a movie while in it, after a hour I then take a hot salt bath for around 30 minutes and keep watching the movie or whatever.

I don't know how well I can answer your questions, as I'm new to lead issues and abatement. You've probably educated yourself on a lot of what I'm going to say, but I'm going to throw it all in this comment, anyway.

I live in a 110 year old house that is basically a ball of lead. The plumbing had lead joints, the service line is old and lead, the windows have lead, the doors have lead, the walls have lead, and the city is concerned that our water mains are shedding lead. And now, my child has a very slightly elevated lead level. Prompted by her most recent blood test, we are attempting a sensible lead abatement plan for our home.

First, figure out where the lead is. You can pick up water testing kits as well as swabs for surfaces. Once you know where the lead is, you can assess your risk and choose an abatement plan.

For instance, we have a small amount of lead in our water, which is likely a consequence of the service line. We got a bid for replacing it, and that was about $10k, plus the cost of fixing the yard that would be torn up. We went with a 10 year filter for the whole house, and that was about $900 including tax and installation.

Use the surface swabs on your windows that were installed before 1980, and if you have woodwork that was painted white, check that, too. It became popular to paint dark woodwork white in the 50s/60s to brighten up houses, and people used lead paint. We have solid wood doors and a ton of trim that is absolutely smothered in many coats of paint, and sure enough, it's super leady.

With windows, the act of opening and closing the windows can cause friction on the paint, which produces inhalable dust. If your family isn't experiencing significantly elevated lead levels, you have the option to simply wipe down the windows with a damp cloth to remove the dust. If you are more concerned, have the budget, or just want new windows, you can replace them. Check to see if your local municipality has a lead abatement grant for windows. In my city, they offer a $350/window grant to replace windows that test positive for lead (along with a few other qualifiers), and that really puts a dent in that cost.

With other painted surfaces, you're likely to be fine with encapsulation, which is a fancy way of saying painting over it. Lead is only really dangerous if you inhale the dust or eat the chips, so if you paint over it, it can't create dust. This will likely mean that you'll need to do a little scraping, which will obviously create dust, so you need to use a quality mask, and then clean like mad when you are done. Wet mop, dry dusting/sweeping is not good enough.

I'm in the process of restoring the woodwork because I prefer a stained finish, and for all the trim that isn't especially decorative or historically significant, I'm just replacing it. For our lovely doors, I sent them out to be dip stripped because it just wasn't worth the risk of my daughter sucking in all the dust while I removed the paint.

Because I have a young child, I'm not fucking around with lead, but the majority of people with lead paint in their homes are going to be just fine if they don't sand lead paint, carefully wipe up the dust with a wet cloth in areas that have lead paint (like windows), and prime/paint over the lead paint.

Got ya, fam.

That'll be the premade solution to start you off. A good rule of thumb would be to buy 3 of those (~150 days worth) and see how you get on with them. If you find that you're seeing decent results, then you can buy the raw powder on that website and start making it yourself at home. Derek from MorePlatesMoreDates has some pretty good write-ups on how to make your own RU solutions, one of which involves minoxidil as the main vehicle.

And no prob. I'd imagine that this would definitely be a useful boost to your regimen.

BONUS TIP: If you really wanna enhance your RU solution, you can add in some Azelaic acid powder as well. A 25 gram bag on amazon will set you back ~$38, but should last you a year and some months. For a 5% solution, both powders should be used at 50mg daily.

EDIT: Forgot to include this other RU solution synthesis article. This guy mixes it daily using a solvent solution, so it's definitely more advanced, but about as comprehensive as you can get. As he also mentions in this guide: "If you want to be hardcore, you could use fin or dut PLUS RU58841/minox/azelaic (home brew as above). If you do this approach as an average guy, I think it would be physically impossible to go bald." There's your motivation!

I'm also on a cistern and use commercial whole-house filters in 2 stages. Stage 1 is a "pre-clean" sediment filter and stage 2 is a carbon filter that helps remove cysts and odors. The pre-filtering helps the more expensive carbon filters last longer. I also have an automatic chlorinator and contact tank for added disinfection (could also use UV) and a RO filter for drinking water. The RO is overkill since water tests fine from the tap (good idea to test periodically!), but peace of mind and all. To maintain a good flow rate, I use 2 filters in parallel for each stage (4 total). It's all easily put together with PVC. I don't have first flush and water can get pretty dirty, but after filtering it's very clean and odor free. Filters typically last about 3 months before the pressure drops too low (for 2 people, so maybe 1 month for you?) and have to be replaced. High efficiency sink and shower fittings help reduce water usage and the effects of the lower pressure. I have the pump run up to 60psi to max out the filter life.

• Filter housings - I like the clear ones to see how dirty filters are getting and also shows how much filth the filters are capturing. Might want to pick up a couple extra housings since they need to be cleaned and cleaning is much easier with running water. I also use gasket grease and a filter wrench (they can get tight).
  
  
• Sediment filter - stage 1
  
  
• Carbon filter - stage 2 - The 0.5 micron removes cysts (things that can make you sick like Giardia and Cryptosporidium)
  
  
• Test kit
  
  
• Shower head
  
  
  
  

All? Every store in my area has a water refill station. In my area it's near the coffee section. I'm not sure how much it costs, but it's way cheaper than buying bottled water.

That being said, why not just get water from the tap? If you're worried your water might be unsafe (most likely it's just fine), then test it. A quick search found this affordable test kit, which will tell you if you need to get a more comprehensive test done. Most likely you'll be well within safe standards and can safely use your city water.

Personally, I use a filter at home because I don't like the taste of our water. We have hard water, and there are still traces of something after our water softener. Our water is perfectly safe to drink, but a filter makes it much more palatable, so we use one. It's way cheaper than bottled water and way more convenient.

despite people telling you this cant be done this can easily be done with the enzyme trypsin . trypsin cleaves lysine amino acids. you can buy this pure from amazon .


enzymes are like little robots from the movie wall-e. they continue to do a job until it is done or they are denatured/inhibited. this means that you could use a any amount to get the job done but the less you use the longer it will take.

Trypsin is the ideal enzyme because it will cleave lysine and optimal pH is that of tap water.

IMO this is the best option due to your limited chemistry knowledge.

preheat a thermos to about 40C take a small quantity of about 100-200 mg of enzyme and the contents inside one vyvanse pill. place them contents in the thermos and seal the thermos with lid for about 2 hours ( it doesnt matter if it is longer, you can do it over night if you wish). now, heat the contents until boiling, this will denature the enzyme which is critical because you dont want to mess with enzymes and the stomach (ie ulcers). cool, consume, and enjoy.

Alright here we go

1. The acid can either be muriatic ferric chloride. Ferric chloride being far safer and much much more common. Dip it and let it sit in the acid for 30 minutes. Take it out and spray it with windex or something else to neutralize the acid. Sand it lightly after with very high grit if you’d like a lighter finish don’t if you’d like a darker finish.
   
   2 i get my ferric chloride off Amazon
   Here’s the exact stuff I use MG Chemicals 415 Ferric Chloride Copper Etchant Solution, 945mL Liquid Bottle https://www.amazon.com/dp/B005T8Y20W/ref=cm_sw_r_cp_api_i_cw1lDbFSXD42R
   
   3 usually people use ceramic “pellets” but basically anything hard will work the bigger harder and sharper the stones or bits are the tougher the finish.
   
   4 for the stoning part take the blade and stick it into a vibratory tumbler or a rock tumbler I believe with some water for how ever long. Longer is more scratches less time is a less scratched look. The tumbler can be found for about $55 at harbor freight https://www.harborfreight.com/5-lb-metal-vibrator-tumbler-67617.html
   
   
2. Cut the deer antler length wise to get two sides that you can then epoxy and pin onto the handle
   
   A fair price for that would be about $250-$300 but if you get some good fishing spots and because it’s for a buddy I’d charge $200-$225 probably up to you
   
   Hope this helps

Hmm, I'd be shocked if one of us discovered a substance we could get at home that would create an as-of-yet-undiscovered precipitation reaction that would precipitate chloramine out of water! The reaction with citric acid you mentioned, is another one I now remember I've heard. All the points you make are right on, so if you figure something out, let us know! BUT the first step in my mind is finding a way to verify any potential results, so we're back to a cost effective way of measuring chloramine levels in a given water sample.

The cheap test strips for drinking water and aquariums seem to only test for chlorine (http://www.amazon.com/dp/B000FBMAVQ/)($13), and the expensive ones seem to indicate they CAN be calibrated to check for chloramine (http://www.amazon.com/dp/B00I4TFU1I/) ($1,099). This seems made specifically to test for chloramine, but it's unavailable (http://www.amazon.com/dp/B00R3EF7ZY/).

I'll bet small quantities of citric acid are fine, and small amount of humic acids are definitely beneficial (humic acid is naturally occurring in compost and is great for soil). How much is too much, idk, since I don't add any directly/intentionally.

This one, First Alert WT1 Drinking Water Test Kit. The guy at the environmental test company said those kits aren't really sensitive enough to get more than a "that's pretty good" or "that's pretty bad" despite the results you get. He said they tend to be consistent, though, so if you get good results you should be good, and if you get bad results, you should call someone like him. If you get fuzzy results, it comes down to how strongly you feel about getting it officially tested.

Yeah, the "flammable tap water" thing was from up in my area, Weld County. The situation was that all of these folks used well water for their houses, and they had higher-than-normal levels of methane gas in their water. It was a big hit with the local media, but the kerfluffle died out not too long afterwards.

I think you'll find a lot of information if you check out Denver Water's page on Water Quality - they provide information on the treatment process and the results of their tests. You can probably also request the water test results in print (In Greeley, we get them once a year with our water bills).

All in all, I've lived here a long time, and I've never had a problem with our water anywhere. In my opinion, it seems like municipalities in Colorado are much more concerned with water and water quality than in other places in the US I've lived previously. Heck, Coors even advertises that their beer is brewed with fresh "cold Rocky Mountain water"!

Feel safe with your water. If you're still concerned (or want to prove to your mom that the water's safe), you can always buy a water testing kit, although I don't know how accurate or effective they are, never having used one myself.

Thanks again, this is all very helpful. I was thinking i might have to go ACS, and Reagent grade since Spirulina absorbs heavy metals apparently.

I was kinda torn between getting cheaper ingredients now for fish use and upgrading later for selling quality, but now I think I'm defiantly looking to be able to sell (Spirulina and Zarrouk). So I'll be looking into the ratings. However, resources like your link will be useful for cheaper options for fish food. Tbh I'll probably experiment more with common garden fertilizers and such for this purpose.

Also, I'ts kinda awkward to be searching for "food grade" Boric Acid. So far even Quality ACS Boric Acid warns not for Food use.

​

For others looking, so far the items I've found and am considering purchasing are as follows:

Dipotassium hydrogen phosphate

Sodium nitrate

Potassium Sulfate

Calcium Chloride

ethylene diamino tetracetic acid

​

Solution A:

Boric Acid

Manganese (II) Chloride Tetrahydrate (MnCl2 . 4 H2O )

Zinc Sulfate

Copper Sulfate

Molybdenum oxide

I'll try to make a complete edited list after some more research.

Yes, there are those but you mentioned filters. I find the big bottles of water to be overwhelmingly more common, and you can just flip a coin as to whether the company that bottles it follow regulations. I'm actually taking this back from meiguo to make sure the company my school buys from is okay, as I've noticed the plastic circles you punch through have become almost too easy to open recently and one was already opened when it was delivered.

First Alert WT1 Drinking Water Test Kit

https://www.amazon.com/dp/B000FBMAVQ/ref=cm_sw_r_udp_awd_OXL5tb0YNPYD8

First Alert WT1 Drinking Water Test Kit. I live in a 100-yr old building with original plumbing so I bought this and tested the water. Everything came out well within EPA standards. Our city water (San Francisco) is among the best in the country so your mileage may vary.

This is getting pricey:

Solution A:

• Potassium Iodate $40 (this is for 100g and the video calls for 43g).
  
• Sulfuric acid $20 I don't think this is concentrated enough to do the trick. This might be a showstopper since, even if I could get ahold of a higher concentration, I've heard too many horror stories about working with undiluted sulfuric acid that I may just want to pass.
  
  Solution B:
  
  
• Corn Starch $8
  
• Malonic Acid $10
  
• Manganese Sulfate Monohydrate $15
  
  Solution C:
  
  
• Hydrogen Peroxide $17
  
  
  And distilled water is a couple bucks per gallon at the grocery store. Looking at around $100, and that is assuming I get all the ingredients right the first time and don't have to reorder any of this and ruin some of my ingredients in the process. Many of the ingredients will have leftovers, but the potassium Iodate seems pretty expensive for such a small amount that I'll use half of just to make one batch.
  
  EDIT: Not too surprisingly, it seems like the acids and peroxides I've listed may not be nearly concentrated enough to do the trick.
  
  EDIT2: Updated hydrogen peroxide link to a 35% concentration instead of first aid style which is 2-3%.

I used some circuit board etcher from Amazon (Ferric Chloride). I cleaned the clip with acetone, dipped it in a 70% acid / 30% water mixture for about 20 seconds, let it air drip for 10 secs, rinsed in the tap and repeated twice. Then I dryed it well and sprayed it once with gun oil. Looks great and feels great!

“Drug bad, therefore illegal” IS NOT LOGIC.

Sorry for the caps, but i’m just getting sick of seeing this on this sub. The alcohol industry is worth $1.3 trillion fucking dollars. $1.3 trillion!! And you want to give black market groups this economic opportunity. With this kind of money, cartels would be more powerful than a vast majority of countries. Instead of ruling from the shadows like they do now, corrupting politicians and silently killing opponents, they could just straight up take over countries. Latin america in particular would get straight up annexed. Why is this cool and good to you?

Furthermore, people would start drinking 2m2b. Some context here - ever heard of spice? Synthetic cannabinoids? These are part of a class of drugs called “research chemicals”. Research chemicals are created by overseas scientists (mostly chinese). What they do is take illegal drugs, and slightly tweak them, producing an analogue of the drug that’s also psychoactive. These analogues are technically legal, simply because politicians don’t know about them. And 2m2b is an analogue of ethyl alcohol. And look, you can buy this shit legally, on amazon. $165 for a liter sounds steep, but a mere 3 milliliters will have you drunk for 12 hours. That’s the potency we’re talking. People would be chugging this shit left and right, and because nobody teaches you the potency, a lot would learn the hard way, drinking 2m2b like it’s ethyl alcohol and dying. Why is this cool and good to you?

This one's worked fine for me in the past, it gave me no false positives. I knew I could trust it because the region in which my old houses were located was notorious for its incredibly hard water, and that was the only factor for which my results came back as positive.

https://smile.amazon.com/First-Alert-WT1-Drinking-Water/dp/B000FBMAVQ/ref=pd_sim_79_5?_encoding=UTF8&psc=1&refRID=BNCFD5MHAKWG0RD9Z30X

It cost like $15 to buy a water test. I drink a lot of unfiltered water so I got one. The test said I'm all good. Worth buying and seeing if you should invest in some type of filtration system.

I suspect it would be. Kinda in the realm of sweet soy sauce.

I mean, you could just do it yourself. Pure lead is quite easy to obtain, as fishing weights etc, and you just need to grind it to a powder, and then blow torch it, at above 600°C, until you get an off white/beige powder. That's PbO.

Or if you life somewhere that lead naturally occurs, it'll be lead sulfide, which turns into PbO at 1000°C under air.


You obviously don't need much, just a few grams of lead filings would be enough to create 50 mg for a 'safe' taste test.


Once you have the PbO, you should be able to just mix it was glutamic acid in water, and obtain lead (ii) glutamate, analogous to how lead(ii)acetate is formed.




Alternatively, just buy glutamic acid and lead oxide on amzn: glutamic acid

lead II oxide

I always get a laugh when I see the "Customers also viewed" section of Palladium Chloride on amazon:

I'm not saying buying these would get you arrested, but it's not unreasonable to assume your name/address would be placed on some list that would cause it to pop up bright red on the cops' computer when they look you up. Immediate cause for CD/investigation - no. But can it be used as probable cause for a search warrant? I think so.

Is there a problem with me just buying this and experimenting with different oils to see what works better?

Edit: This would probably look better wouldn't it...

I think you're right, my chemistry is the suck sometimes.

Black iron oxide is pretty cheap too. Amazon has that for 20 bucks for five pounds with free shipping.

Start there, 5 stars, it will have links to other test kits if you don’t trust that one.

Amazon sells well water test kits. Tests for a number of things - lead and other metals, bacteria, etc.

Edit: I think this is the one I used.

Might be worth doing a test of your water. Any alarming results could be taken to Public Works to hopefully find a solution to the problem.

Naw son. Get this. It's a plant growth hormone. It'll make that grass into a jungle.

I’ve only ever done it on a laboratory scale, so if you’re using a reasonably large tank, I don’t know how well it will work.

You need a gas canister of nitrogen or argon. You can buy one at a local gas supply store like praxair. You might also find one online. Run some hosing from the gas canister to the bottom of your tank and open a steady bubble for 30min or so.

Wikipedia says that ammonium sulfite will consume oxygen from water. I’ve never tried this, but if you don’t mind introducing salts into your water, this may be simpler.

Well, IF the brass used has lead in it (not all brass does, and it is used less and less in brass) the small amount of mineral scale tends to form a nice barrier preventing it leaching into the water. A few flushes should work. If you are worried, test it. https://www.amazon.com/First-Alert-WT1-Drinking-Water/dp/B000FBMAVQ/ref=sr_1_3/141-8508703-2370814?ie=UTF8&qid=1502944258&sr=8-3&keywords=water+lead+test+kit

Test your water for lead if you are worried about it. That's really the result you care about. There may be small sections of pipe or solder that contaminate the water even if you don't have large sections of lead pipe.

There are test kits you can buy. For example:

http://www.amazon.com/First-Alert-WT1-Drinking-Water/dp/B000FBMAVQ

Make sure you find one that tests for the things that concern you. There are also labs that you can mail water to but I didn't quickly find a link.

nice. Tips: you can keep Ferric Chloride solution in a ice cream bucket, i have had mine in one for a few months with no problems. also you can also use a soda bottle for dipping the blade.

For engraving you cant go wrong with a rotary tool as its the easiest way to do engravings. ghaa my engraving tip busted well i was doing the engraving on my latest blade as i developed a makers mark and put it on all my blades. so well I got it on it I screwed up the engraving so I did not do the best i could.

also amazon sells ferric chloride so here's a link: https://smile.amazon.com/gp/product/B005T8Y20W/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

For etching resist you can use acrylic paint and I hear you can use electrical tape but have not tried it yet.

Well first off I don't do inorganic, so I can't advise you on how to perform the reaction. I can, however, advise you on some things you shouldn't do. If Fe(0)+HCl->Fe(II)Cl2+H2, then you've produced some explosive gas, but that's probably low concentration and you can handle H2 in a reasonably vented area. The bigger problem is the implication that 2Fe(II)Cl2+H2O2+2HCl->2Fe(III)Cl3+2H2O. While that seems credible, adding peroxide to a solution containing HCl will also produce chlorine gas, which is very toxic and probably shouldn't be performed outside of a controlled area, especially without a trained chemist.

Also, it looks like you can get it shipped to Hawaii from Amazon.

Honestly we should start some type of crowdfunding for it.

You don't have to inject Febreze by the way.

Also the amounts that caused liver damage and hearing loss were a shitload per kg of body weight. You'd probably do best by going on a low fat, vegan type diet and trickling this into your blood stream. Just a guess though.

Someone said perhaps the delivery mechanism could be patented. Since it's not readily absorbed by ingestion and I think you have to have an aerosol version to get it into the bloodsream via snorting, they should focus on making pills you could swallow that would get into your blood stream. They could make a ton of money just selling a light preventative.

A liter is $15ish and will go a very very long way with etching knives.

Just be sure you do some research on safe handling. Use plastic containers not metal or glass. And be careful. It's a relatively safe and weak acid. But it's still acid and can hurt you if handled poorly.

How bad are these? http://amzn.com/B000FBMAVQ

Here's the 2014 Water Quality Report. It's a good read.

The bulk of the water testing takes place directly at the 3 major water facilities in SD. As you may already know the lead contamination in Flint did not happen at the water treatment facility, but rather in the pipes that lead to homes. The city inadvertently changed the water pH and failed to add an additive that would prevent the old pipes from corroding.

The way the city of San Diego test for these metals is by sampling the water in 50 homes. According to their results, we are good and the water is safe. If you want to do your due diligence, buy one of these cheap drinking water tests that include testing for iron, lead and copper among other things.

I did, and confirmed some of their results.

EDIT 2: Perchlorate is more of a health concern, and it's not mentioned on the report. Is it regulated by the city?

• Perchlorate is a salt (ClO4^−) that is naturally occurring in SD; and also a byproduct of military rocket fuel, and fireworks. It affects the thyroid gland can decrease production of thyroid hormones.
  
  
• California EPA reports peak concentrations in San Diego that average 9.9μg/L. MCL is currently 1μg/L and was lowered from 6μg/L a couple of years ago.

Thanks. I live in an old building. I basically want to do a test for things that will kill me in the short or long run.

I found this.

and this

Hopefully it's enough.

I realize this sounds crazy considering 99% of tap water is safe to drink (according to the comments in this post). I'd rather be paranoid then dead.
