The authors studied the influence of the roughness factor of platinum electrodes on the basic features of benzene and phenylacetic acid adsorption. To elucidate the effect of molecular size on adsorption the results obtained were also compared with similar results for n-hexyl alcohol. Platinum electrodes with different roughness factors were prepared by electrodeposition from solutions with 3 mass % of H/sub 2/PtCl/sub 6/ at E/sub r/dep = 0.2 V. The base electrolyte was 0.5 M solution of specially pure sulfuric acid in twice-distilled water. In studying the adsorption of benzene and phenylacetic acid they used the method of fast cathodic and anodic pulses. All potentials are reported relative to a reversible hydrogen electrode in the same solution.
