Abstract
The extraction of mercury by inert solvents has been investigated as a function of the hydrochloric and sulfuric acid concentration in the aqueous phase. It was found that the extraction of mercury with kerosene is adequate at low hydrochloric acid concentrations but decreases with the increasing acid concentration. In the case of sulfuric acid a maximum and/or a minimum are noticed. The presence of trace halides in the aqueous phase changes the shape of the relation between the distribution of mercury and the sulfuric acid concentration in the aqueous phase. The extraction of mercury by neutral, anion and cation exchange reagents was also investigated.
