Extracting mercury from contaminated water

[@AlphasysNl]

Waste disposal and management is an often forgotten and obscured part. People love to see reactions and might think to do these things themselves, without thinking about the disposal process. This video is invaluable, since it shows it's not all fun and games.

[@NileRed]

I agree!

[@user255]

Yes, good reason not to experiment with mercury, lead, etc.

[@Mephistahpheles]

Waste disposal is easy. 1) Political donation 2) Dump it anywhere

[@that1nerdyblackgirl736]

That's why i really rather watch it than to do the experiment

[@davegiard2221]

What scares me is imagine all the people who DONT see this and just flush waste down the drain. Its a shame people can be so ignorant.

[@theCodyReeder]

I usually just add a wad of bare copper wire to my waste mercury jug and get pure mercury metal in one step, But I have always wanted to see this method. Any chance you can convert it to the red mercury sulfide? I haven't figured out how to do it yet.

[@Seff2]

I always wondered how you clean up your waste cody :D

[@NileRed]

It's funny that I honestly never thought of just adding a metal to reduce it. That is probably the better way, ha. I imagine is takes a long time though. I think to convert it you need high temp and pressure or something. In the end, the chemistry of the two kinds are pretty similar. Why do you want the red sulfide? As a dye or colorant?

[@amosz5726]

I'll be trying to do this pretty soon, actually. I'm after a full set of historical paint pigments and so I'm intentionally making mercuric sulfide for it. There are vague references to the black sulfide being heated to temperatures in excess of 300 degrees celsius to convert its crystal structure to that of vermillion, and even to sublimation occurring at those temperatures. This could be useful for separating the mercuric sulfide from your celite, NileRed. I'll let you all know of my findings when I get around to it.

[@MuzikBike]

I think it would be pretty interesting to see a liquid metal being cemented out onto a piece of solid metal. Especially copper with its deep, cold-coloured ions. Would the Hg bead up and only fall when it gets big enough? Or would it appear absolutely everywhere in the form of microscopic drops like condensation?

[@CollegeChemistry]

[@Hawk013]

I understand a lot of the basic chemistry, and the rudimentary molecular physics behind it, but my memory is so far gone that I can't retain the formulas or even the chemicals for more than a minute or two. The ideas, yes, but not any specifics. The organic chemistry just completely loses me after two or three reactions. Still immensely interesting though.

Great video, as always. I have suggestion for future synthesis - the Crystal violet dye, also known as gentian violet. It can be used for staining biological samples (like Eosin), it has some antibacterial effects and it can be used as pH indicator. In strongly acidic solutions, the color of the dye changes from violet to green and to yellow. In basic solutions, it decomposes and becomes colorless.

[@irvingkurlinski]

Very practical use of chemistry and educational from several standpoints. Thanks for your posting. After thought: If you sandwich the diatomaceous earth between two sheets of "fast" filter paper it is easier to deal with.

[@NileRed]

that is a very good point. I didnt even think of that

[@jakers141]

lmfao I wrote the exact same comment

[@brewer13210]

When filtering with DE (Diatomaceous Earth) you can continue to add small amounts of DE while you are filtering to keep the filter surface from being blinded. This keeps the filter process from slowing down.

Alot of mercury sulfide would still go through it and into the sand tho. But it could increase the yield of non-mixed sulfide.

Just treat it with sulfuric acid to about 2 pH, add some iron, raise the pH to 7 using Sodium Hydroxide, then add Sodium Hydrosulfide flakes at about 1-2.5% bv. Raise the pH to the desired precipitation pH for Mercury. Vacuum filter through a diatomaceous earth cake, preferably a cake which was deposited over a small rotary vacuum drum.

The quantitative precipitation of mercury sulfide works at a pH = 0 - 1 as well. No need to put in large quantities of NaHCO3. During the ion separation procedure in analytics you will bubble in H2S-gas into the acidic solution with a pH of about 0-1. HgS 's solubility product is VERY low!😉

another thing about that black water that was cause by the use of tap wter as a solvent: the finer the particles of metals become, the blacker they get ... the same thing happens with salts (exceptions do apply of course).
