Abstract

Basic ideas, principles, potentialities and recent developments of chronopotentiometry, as a method of electrochemical studies, are reviewed. Single and complex mechanisms of electrode reactions are discussed and the sequence of occurrences on the electrode during galvanostatic non-steady state electrolysis analyzed. Derivations of fundamental relationships, τ = f( i) and E = F( t). (transition time-current and potential-time) are discussed on the same basis. Applications of the chronopotentiometric method of study in the following fields are reviewed: electroanalytical chemistry, diffusion, electrode kinetics, mechanism of electrochemical reactions, adsorption of electroactive species and the study of complex ions. Instrumentation and experimental technique are briefly reviewed.
