Electrochemical monitoring of biogenic microelements

Abstract

This paper reviews literary data on electrochemical monitoring of biogenic microelements in natural and industrial objects. Special attention is paid to the questions of the trace determination for a number of transition metals by stripping voltammetry (SVA) after the adsorptive enrichment of these elements as dimethylglyoxime (DMG) complexes on the surface of a working electrode. The analytical possibilities of adsorptive SVA with the use of mercury-based and mercury-free electrodes are compared. The paper is dedicated to the memory of Vadim Mikhailovich Ivanov.
