Sažetak
A theoretical analysis of reversible and kinetically controlled electrode reactions in conditions of alternative differential multi-pulse voltammetry (ADMPV) is presented. The degree of reversibility, as well as symmetry of the electron transfer reaction, can be estimated by visual inspection of the ADMP voltammogram. The values of electron transfer coefficient and the standard rate constant of a simple electrode reaction Ox + ne− ⇄ Red, can be determined from the slope of linear dependence of the peak currents ratio on the logarithm of pulse duration. The criteria for recognition of reversible and kinetically controlled electrode reactions by alternative differential multi-pulse voltammetry are given.
