Abstract

The potential and concentration dependence of the adsorption of glycollic acid has been investigated on platinized platinum electrodes in 1 M HClO4 supporting electrolyte by a tracer method. The potential dependence of the adsorption is similar to that observed for acetic and oxalic acids and inorganic anions. Phenomena occurring in the course of the adsorption of alcohols cannot be observed. On the basis of this observation and therstudy of the concurrent adsorption with acetic acid it may be assumed that there is no interaction of the -OH group with the surface, i.e. the adsorbed glycollic acid is oriented to the surface with the -COOH group.
