Time effects at the adamantanol-1 adsorption on silver electrode: Comparison of impedance data with results obtained by the method of potential shifts induced by laser heating

Using the method of potential shifts induced by laser heating and electrochemical (impedance and voltammetric) measurements on electrodes with mechanically renewable surfaces, the adsorption behavior of adamantanol-1 (AdOH) on the Ag electrode interface with surface-inactive electrolyte (NaF) solutions is studied. It is shown that the kinetics of AdOH adsorption in the potential range of ideal polarizability (near the zero-charge potential Eσ=0) is described in terms of the mechanism of a quasi-chemical reaction Ag(H2O)ads + AdOH = Ag(AdOH)ads + H2O on the energy-uniform metal surface. A phenomenological model that allows one to produce a self-consistent description of time effects observed on a renewable Ag electrode in the potential range of its primary oxidation in solutions containing AdOH was assumed and analyzed.
