Abstract

A simple procedure is suggested by which cyclic voltammograms, CVs, characterizing adsorption processes can be analyzed. Using this procedure, from a set of CVs taken at varied scan rates, two scan-rate independent, hysteresis-free functions of potential can be calculated. One of them characterizes the adsorption kinetics as if surface coverage were zero, the other is an adsorption isotherm. Because of the formal analogy, the procedure is also applicable to CVs of redox systems with a finite quantity of reactants, e.g. surface-confined redox systems.
