THE ELEMENT WITH CONSTANT PHASE SHIFT IN GALVANODYNAMIC MODE

,
 4-8 p.
Abstract
The purpose of this study is to study the behavior of the boundary perfectly polarized electrode – solid electrolyte in the presence of a constant phase shift impedance (CPS) in the galvanic-dynamic mode.
Analytical expressions of the dependence of the potential of the interface of an ideally polarizable electrode-solid electrolyte on time in the galvanodynamic mode in 2 cases are obtained: 1) in the case of a full equivalent electrical circuit; 2) in the case of a reduced equivalent electrical circuit. The complete coincidence of analytical expressions for the potential of the interphase boundary in both cases is shown.

FRUMKIN-MELIK-GAYKAZAN MODEL IN THE CHRONOPOTENTIOMETRIC AND CHRONOAMPEROMETRIC MODES

, ,
 4-13 p.
Abstract
This study analyzes the behavior of a metal electrode in an organic electrolyte containing a surfactant with the property of adsorption in chronoamperometric and chronopotentiometric modes.
Analytical expressions of dependence of potential of interfacial boundary metal electrode-solution of indifferent organic electrolyte on time; and also analytical relation of dependence of current passing through a cell on time in chronoamperometric mode are received.
Graphoanalytic method established that the dependence of the potential of the interface metal electrode-solution indifferent electrolyte, which has the property of adsorption on the electrode, in the Frumkin-Melik-Gaykazyan model in chronopotentiometric mode is exponential. The dependence of the current through the cell on time in chronoamperometric mode is also exponential.
