Abstract

The influence of adsorption of the electroactive species on the square-wave voltammetric responses of two different EC mechanisms is theoretically studied. Theoretical models for the EC electrode mechanism, coupled with adsorption of the reactant but not of the product of the redox reaction and for the surface EC mechanism in which both the reactant and the product are strongly adsorbed, are developed. The reversible and the quasireversible redox reactions of both electrode mechanisms are considered. Relationships between the properties of the SW response and the parameters of both redox reactions and SW excitation signal are analyzed. The theory is compared qualitatively with the SW voltammograms of azobenzene recorded in an acidic medium.
