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.
