INFLUENCE OF EXPERIMENTAL CONDITIONS ON THE CYCLIC VOLTAMMETRIC RESPONSE OF MULTILAYER SURFACE MODIFIED ELECTRODES, II EFFECT OF COUNTER ION CONCENTRATION, TEMPERATURE AND SWEEP RATE
The combined effect of counter ion concentration, temperature and sweep rate on the cyclic voltammetric response of multilayer modified electrodes has been studied on the basis of data obtained for tetracyanoquinodimethane and poly(vinyl-ferrocene) polymer film electrodes, as well as for modified Ni electrode.It is established that the counter ion concentration influences to a great extent the cyclic voltammetric response, which is probably due to the swelling of the polymer film.With increasing counter ion concentration a shrinkage of the polymer layer and accordingly, an increase in the concentration of redox sites in the film occurs.Although this may cause an increase in the rate of electron exchange between the neighbouring redox sites, permeability of the film in respect to the solvent and ions decreases.This effect may be the reason for a diffusional behaviour which can be observed on using concentrated supporting electrolytes even at low sweep rates and high temperatures.The apparent activation energy of the electrochemical steps depends on the counter ion concentration and sweep rate.On the basis of the temperature dependence of peak potentials, an estimate can be made for sweep rate at which surface behaviour can be expected.
