Abstract
Abstract An indirect atomic absorption spectrophotometric method for mercury has been developed on the basis of solvent extraction chemistry. Mercury(II) was converted into a bromo-complex anion and extracted into 1,2-dichloroethane with the 2,2′-bipyridyl-zinc chelate cation. The resulting zinc in the extract, which was equivalent to a specific amount of mercury, was determined by atomic absorption spectrophotometry. The sensitivity for the determination of mercury could be enhanced to the level of zinc by the proposed method.
