Treatment of mercury contaminated aqueous media |
摘要 |
A technique for removing substantially all the elemental mercury from a mercury containing aqueous media by adjusting the pH of the liquid to the range of 7-13, adding a polysulfide in an amount sufficient to combine with the elemental mercury to form a mercury sulfide which is precipitated and preventing the mercury from being resolublized.
