Abstract
An equation that describes the electrodissolution of a film of a difficultly-soluble compound from the surface of metallic electrode during a linear potential scan is derived and solved numerically. The model accounts for a nonuniform deposit distribution over the electrode surface and for the diffusion of the deposit particles through the film. Voltammograms for the compound electroreduction display peaks whose shape is dependent on the deposit distribution over thickness. The obtained results are analyzed.
