Abstract

Voltammetric behaviour of Ce(IV)/ Ce/(III) redox couple in sulphuric acid and methane sulphonic acid are compared on glassy carbon electrode. Both media exhibit relatively faster charge transfer kinetics. Voltammetric studies in presence of small concentration of naphthalene and p-xylene indicate that these compounds significantly inhibit the electrochemical oxidation of Ce3+ ion thus justifying the necessity for two stage processes. Optimum experimental conditions achieved for electrochemical oxidation of anthracene, naphthalene and benzene to their corresponding quinones and toluene, p-ethoxy toluene , o-chloro toluene, o, m and p-xylenes, 3, 4 – dimethyl anisole and 2-chloro p-xylene to their corresponding aldehydes are also discussed
