Abstract

Sorption of Ca2+ and SO2-4 ions into TCNQ and PVF surface films has been studied under potentiostatic steady state conditions and during potential cycling using a radiotracer technique. It has been shown that the sorption of the counter- and co-ions follows the charge and discharge processes occurring in the film. No sorption of ions has been found in the case of virgin films. No equilibrium in regard with the electrolyte is attained during potential cycling even at slow sweep rates. In the case of TCNQ electrodes the equilibrium concentration of counter-ions in the film is associated with the equilibrium concentration of different dimerized species.
