TRANSIENT METHODS FOR ANALYSIS OF ELECTROCHEMICAL KINETICS

Abstract

The report includes a review of relaxation methods and describes the principal achievements in the following areas: Instrumentation: Two new circuits for the independent control of two working electrodes (ring-disc assemble) in the same electrolyte are described; Characterization of mercury batteries by pulse techniques: It was proved that pulse methods can give promising results concerning the state of charge of mercury batteries; Electroreduction of m-dinitrobenzene: The mechanism of m-DNB reduction in Mg(ClO4)2 solution correspond to an ECECE mechanism. An electrode mechanism consistent with the experimental data was postulated; Oxidation of zinc anode; The evaluation of oxidation and reduction processes of zinc gave supporting data for an 'adsorption model' instead of the classical 'dissolution-precipitation model' assigned to the passivation of zinc anode; Dissolution rate measurement: Utilizing the rotating ring-disc electrode concept, a new theory for the measurement of dissolution and corrosion rates was developed.
