Liquid Chromatography of Diethyldithiocarbamate Complexes of Cadmium, Lead, Chromium, Cobalt and Mercury

Abstract

The conditions of chromatographical analysis have been studied and the elution data have been determined of diethyldithiocarbamate complexes of cadmium, lead, chromium, cobalt, and mercury using an octadecylsilica gel column and mobile phases water-methanol containing sodium diethyldithiocarbamate. The method is based on a direct injection of aqueous solution of the metal ions into the column and detection of the separated complexes by means of a UV detector in the wavelengths interval of 254-365 nm.
