Components of the Net Current in Differential Pulse Polarography. Part 2. Kinetics and Adsorption

Components of the net response in differential pulse polarography were studied theoretically, assuming gradually changing electrode rate constant or strength of the reactant adsorption. The difference between maximum potential of the peak component and half-wave potential of the wave component appear as an important parameter. From its value, electrode rate constant can be calculated even when standard potential is not known. In a reversible process, effects of the reactant adsorption on the mention separation are less pronounced. The results were compared with some experimentally obtained effects. For deeper insight into applicability of this approach, additional experimentally obtained polarograms (that reflect different potential/timing parameters or changing character of the electrode process) should be studied in terms of their components.
