Extraction of zinc, cadmium and mercury salicylates.

A systematic study of the solvent extraction of Zn, Cd and Hg salicylates is reported. Optimum conditions for extraction and separation of Zn, Cd and Hg are evaluated from a critical study of pH, sodium salicylate concentration, mesityl oxide concentration, period of equilibration, and effect of diverse ions. A separation scheme is described and results are reported for analysis of synthetic mixtures and commercial samples.
