In basic media pyruvate anion oxidizes on a polycrystalline gold electrode. The number of electrons involved is two per pyruvate molecule, and the final products are acetate and carbonate. The oxidation is strongly inhibited by the appearance of gold oxides, and a self-inhibition process takes place.

The electro-oxidation mechanism of glyoxal on a polycrystalline gold electrode in acidic solution has been studied. The oxidation takes place in the potential range at which OH and oxide coverages are formed and proceeds via a sequence of chemical and electro-chemical steps with the formation of oxa
Voltapams of L-ascorbic acid on a gold electrode show the existence of two oxidation waves but no reduction wave. An analysis of the i-E curves was carried out together with the Tafel slopes and reaction orders. The products from the first oxidation were identified by paper chromatography. A scheme
