Abstract

The potential and concentration dependence of oxalic acid adsorption has been investigated on platinized Pt electrodes in 1 M HClO4 supporting electrolyte by a tracer method. It has been established that there are two types of potential-dependent adsorption of oxalic acid in the potential range under study (0-600 mV). The adsorption between 200 and 600 mV is a mobile one. The potential dependence of this reversible adsorption is similar to that observed for acetic acid and anions. At potentials more negative than 200 mV the adsorption is irreversible. The effect of anions (Cl- and HSO4 -) on the reversible adsorption of oxalic acid was studied.
