A unified treatment for potentiostatic voltammetry at spherical and planar electrodes

Abstract

A theory for a unified electrode model which takes into account, among others, four kinds of electrode models, namely, stationary plane, stationary sphere, expanding plane and expanding sphere, has been developed. Equations for potentiostatic voltammetry applicable to this electrode model have also been derived. These equations are general and can be applied, for example, to a stationary plane electrode, to a stationary mercury drop electrode (SMDE), and to the two models of dropping mercury electrode (DME), expanding plane and expanding sphere. Examples which illustrate the use of these equations are shown.
