Abstract

Abstract: In this paper the theory of quasi-steady-state reversible wave in linear sweep, derivative and semi-differential voltammetry at ultramicroband electrode is described.The properties of the current-potential curves are discussed.Experiments were carried out on an oscillopolarograph to verify the theory.The theoretical conclusions are in good agreement with experimental data for the oxidation of K₄Fe(CN)₆ in 0.5 mol/L KCl solution at gold ultramicroband electrode.

Key words: Linear sweep voltammetry, Quasi-steady-state reversible wave, Ultramicroband electrode
