Sažetak
In this communication a basic theory of cyclic differential pulse voltammetry (CDPV) of a quasi- reversible electrode processes: Ox + ne- ↔ Red, is presented and experimentally verified. It is assumed that both the reactant Ox and the product Red were soluble in the aqueous electrolyte and did not adsorb on the electrode surface. The potential waveform of CDPV is presented in Fig. 1. It includes change of the scan direction at certain potential more negative than standard redox potential. The effect of dimensionless kinetic parameter on the shape of the current- potential curve is examined. Furthermore, a relationship between peak potentials and the logarithm of pulse durations in CDPV is analysed theoretically and the critical kinetic parameters are calculated for the standard experimental conditions. On the basis of critical parameters, a method for the determination of standard rate constants and transfer coefficients is proposed
