摘要：

Long term electrolyses of aqueous solutions of D-gluconic acid, in alkaline medium, were carried out on smooth and upd Pb modified Pt electrodes. The reaction products in solution were analysed by ionic chromatography. It was found that the kinetics of oxidation and the orientation of the reaction depend strongly on the catalytic properties of the surface. On a smooth Pt electrode, the main products of D-gluconic acid oxidation are oxalic, tartaric, 5-keto-D-gluconic and D-glucuronic acids, while on Pt-Pb electrodes, D-gluconic acid is oxidized selectively to 2-keto-D-gluconic acid. This product and other by-products were identified by GC-MS coupling techniques.
