Reverse Scan as a Source of Information in Square Wave Voltammetry

Marina Zelić

Abstract

Under the influence of recently published articles, reverse scans in square wave voltammetry were applied in a study of Eu3+/Eu2+ redox system at increasing concentrations of several electrolytes, and gradually changing frequency or step potential. The electrode response is highly affected by all these factors and two peaks can appear though only one electroactive species is present in the solution and one electron included in the process, whereas adsorption of the reactant or product is not pronounced. Scanning in both directions appears as a potential tool for kinetic studies of the electrode processes although in the studied system its practical application meets various problems.
