Cation-exchange separation and determination of silver in admixture with mercury(II).
Cation-exchange separation of silver from mercury(II), copper(II), cobalt(II), nickel and zinc, based on the differences in the stability constants of the complexes formed by these elements with EDTA at pH 4.6, is described. Silver is eluted with 16% nitric acid and is determined by Volhard's method.
