Abstract

The electrochemical oxidation behavior of p-cresol on platinum anode had been investigated by cyclic voltammetric method for the variation of concentration, scan rate of potential, temperature and pH of electrolyte. The oxidation potential of p-cresol was dependent on the electrolyte until the pH=11.5, but in basic solution over its, it was held at o.40V(vs. SCE). A diffusion was rate determining step of oxidation as irreversible reaction by the transfer atone electron. The current of peak was proportional to concentration of p-cresol until the 0.1N and optimum concentration was found to be about 0.1N. The activation energy was calculated for 5.8kcal/mol from the plot of log $I_l$ vs. 1/T.
