Abstract: The electrochemical oxidation-degradation of phenol in aqueous solution were studied on Ti/PbO2 and Ti/Ru-Ti-Sn oxide coating electrodes. The effects of different electrodes on the electrochemical oxidation reactions and reaction intermediates of phenol were investigated by using UV-Vis spectroscopy. The electrogeneration of hydroquinone and pyrocatechol were detected by the method of high performance liquid chromatography(HPLC). The results show that the oxidation-degradation of phenol in aqueous solution are attributed to a further oxidation of hydroxylated products(hydroquinone and pyrocatechol).
