Abstract

Solutions have been obtained to the problem of steady-state transport to an inlaid disc electrode subject to control by diffusion, thermodynamics, kinetics, or any combination of these three constraints. Thus we are able to predict the exact shapes of steady-state voltammetric waves under reversible, irreversible and quasi-reversible conditions. Our treatment also provides information about the non-uniform distributions of concentration and current density across the face of the electrode. Novel aspects of voltammetry at microdisc electrodes are discussed and advantages of steady-state measurements are emphasized.
