METHOD FOR REMOVING AND/OR RECOVERING MERCURY

摘要

The present invention relates to a method for removing and/or recovering mercury from natural water or wastewater contaminated with mercury, characterized in that the method comprises the steps of: (a) extracting the mercury from the natural water or wastewater by adsorption onto an anion exchange resin; and (b) removing the adsorbed mercury from the loaded anion exchange resin by elution with a complexing agent selected from a sulphur-containing inorganic anion and an organic ligand containing one or more donor atoms selected from oxygen, nitrogen and sulphur.
