Abstract

Abstract The preparation and application of mercury-plated, graphite electrodes has been discussed. The electrodes were prepared by controlled.potentialelectrodeposition on the exposed planar surface of a wax.impregnated graphite electrode. The mercury-plated electrodes were evaluated by voltammetric and chronopotentiometric applications to various reversible and irreversible systems. Experimental data were compared to rigorous voltammetric theory. Theory for chronopotentiometric curves at thin-film electrodes with amalgam-forming substances was developed, and experimental correlations with the Cd(II) system were made. In each case correlations were good.
