Treatment of mercury
Thread Content
While doing an experiment, I accidentally poured mercury into the equilibrium vessel; most of it was drained out, but a small amount remained. Water alone isn’t enough to remove it. Does anyone know what to do? :L
Firstly, mercury has a high specific gravity; to remove it from the equilibrium vessel, it is necessary to keep its outlet as low as possible, and the flow path for mercury must be downward and smooth throughout； Secondly, to eliminate the toxicity of small amounts of mercury, sulfur powder is generally used to cause it to react and form mercury sulfide, thereby removing its toxicity.
Be careful of the toxicity of mercury vapor, haha~~
Using sulfur powder is the best method; this is the approach we use when spreading mercury in the laboratory, as it allows mercury to react with sulfur to form mercury sulfide, thereby preventing the mercury from evaporating.
Yes, mercury vapor is highly toxic; it needs to be treated with sulfur
Use sulfur after all; other methods are not thorough enough
Generally, sulfur powder is applied to cause a reaction that forms mercury sulfide, thereby eliminating the toxicity. When operating simultaneously, take precautions to avoid mercury vapor poisoning.
The operation is incorrect. Cover it with sulfur!
If you don’t want to use this mercury, you can cover it with sulfur. But if you still want to recover this mercury, I’ll tell you a method: if you can see it and reach it (I haven’t seen your reactor), you can use a dropper to suck it up. In the past, when mercury was spilled into sinks in laboratories, it was always recovered using droppers.
Well, I plan to use sulfur. The problem is that the openings of my double-loop balance reactors are very small; nothing can be inserted through them. There are also tiny mercury droplets in many corners of the reactors!
Mercury vapor is highly toxic; it’s better not to recycle it – use sulfur instead. Personal safety is the most important thing.
It’s sulfur; using it in experiments, the watermark manometer was broken, by spreading sulfur
