Abstract
The electroadsorption and electrooxidation of 1,3 dioxolane at platinum in 1 M KOH solutions were investigated under a wide range of experimental conditions. The potential of maximum adsorption ( E max ad) is ca. 0.4 V and the degree of surface coverage depends linearly with the logarithm of organic concentration as predicted by a Temkin type adsorption isotherm. The kinetics of the electroadsorption process follows a Roginskii-Zel'dovich equation. From (eps) ad, (eps) ox and analysis of oxidation products a mechanism is postulated which consists of an adsorption with simultaneous dehydrogenation step followed by cycle rupture and electroadsorption and dehydrogenation of further residues.
