Abstract
A general solution for any stepped-potential method in the case of the pseudo-first order catalytic process is presented. This solution is v alid for a reversible redox reaction at a plane electrode whatever the magnitude of the forward and the backward rate constant of the parall el homogeneous chemical reaction. It is shown that polarography, norma l pulse polarography, differential pulse polarography and square wave voltammetry can be analysed easily and uniformly with the aid of dimen sionless parameters. For all these methods, a kinetic zone diagram is also presented. (C) 1998 Elsevier Science S.A. All rights reserved.
