On-line mixing of industrial effluents with a buffered aqueous solution of the water soluble zinc bis<(2-hydroxyethyl)dithiocarbamate> complex (or mixtures of zinc nitrate and ammonium bis(2-hydroxyethyl)dithiocarbamate) leads to the automated formation of dithiocarbamate complexes of metals such as copper, cobalt, nickel, and cadmium.Automated injection of the complexes formed in this way into a slowly flowing (<0.8 mL min-1) 40/60 methanol-water (buffer) solvent mixture followed by oxidative electrochemical detection at +0.9 V vs Ag/AgCl of the dithiocarbamate complexes separated on a C18 chromatographic column completes the development of a highly efficient microprocessor-controlled system for trace metal determination in industrial effluents.The high stability of the zinc complex, the absence of any electroactive ligand, the ability to use water-soluble complexes, and the requirement of only small amounts of nonaqueous solvent allow considerable-improvements to be made in long-term (7 day) monitoring of metals in industrial effluents relative to existing approaches.
