| titleOfInvention | Method for removing trace mercury in water solution |
| abstract | The invention discloses a method for removing trace mercury in water solution, which comprises the following steps of: culturing and analyzing plants grown under mercury environment, utilizing an adsorption and coprecipitation principle to adjust a pH value of water solution containing mercury, adding a coordination complex or a composite formed by a sulphur-containing substance and one or more than two of a zinc-containing reagent, a copper-containing reagent or an iron-containing reagent; and after standing and precipitating, extracting water containing mercury slags, wherein the content of mercury is less than 0.01mg/L. The method is characterized in that: through selection of appropriate sulphur-containing substance, the adding amount of the sulphur-containing substance and the zinc-containing reagent, the copper-containing reagent or the iron-containing reagent, and the pH value of the solution are controlled, so that trace mercury elements in the water solution can be removed; and the materials are economic and easy to get, no any harmful element is added in a system, so that the method is an environmental-friendly and economical processing process. The process can be widely used for treating wastewater containing mercury discharged by the fields such as metallurgy, chemistry, pesticides, pigments, papermaking and leatherworking. |
