Catalytic Adsorptive Stripping Voltammetry at Film Electrodes

Abstract

The recent tendency to replace liquid mercury by less toxic electrode materials has led many analysts to investigate and design various thin film electrodes generated ex-situ or in-situ by electroplating the selected metals at different supports, and to develop new stripping and catalytic adsorptive stripping voltammetric procedures that would use them. The catalytic adsorptive stripping voltammetry (CAdSV) coupling of very efficient adsorptive accumulation of the electroactive species on the electrode surface with the catalytic reaction provides a significant amplification of the analytical response, and, consequently, a considerable decrease of the detection limit, as well as an improvement in the selectivity of the determination. The present article presents an overview of recent progress in the research on catalytic adsorptive stripping voltammetry, with a focus on procedures in which film electrodes were utilized.
