Solid electrodes plated with metallic films

Abstract

This review article surveys basic characteristics and typical electrochemical properties of solid electrodes employed as the supports for the preparation of metallic film electrodes, predominantly of mercury- and gold film electrodes. Individual types of metallic film electrodes are critically compared, including their confrontation with classical voltammetric sensors such as hanging mercury drop electrode or solid gold electrode. Discussed are scope and limitations of metallic film electrodes in anodic stripping voltammetry. Practical applications of these electrodes are demonstrated using some typical examples based on authors' experience with mercury- and gold film plated carbon paste electrodes.
