ABSTRACT:
A method for removing mercury from a sulfuric acid solution including the steps of mixing the sulfuric acid solution with a hydrocarbon solution to form a chemical complex containing mercury. The hydrocarbon solution typically contains a lower alcohol and a halogen component. The mercury complex is removed by the addition of activated carbon and subsequent filtration. Alternatively, solvent extraction, volatilization or other suitable separation techniques can be used.
