ANDRADE, Leonardo S. et al. Development of a HPLC method to follow the degradation of phenol by electrochemical or photoelectrochemical treatment. J. Braz. Chem. Soc. [online]. 2006, vol.17, n.2, pp. 369-373. ISSN 0103-5053. http://dx.doi.org/10.1590/S0103-50532006000200022.
The development and validation of a HPLC method to follow the degradation of phenol by electrochemical or photoelectrochemical treatment are described. This method, which allows determining amounts of phenol, p-benzoquinone and cathecol in electrolyzed or photoelectrolyzed solutions, was used for analysis of reaction intermediates during electrooxidation or photoelectrooxidation of phenol using a Ti-Pt/PbO2 (obtained by thermal-electrochemical or electrodeposition methods) or Ti/TiO2 doped with Ga3+ (obtained by thermal decomposition of precursor salts) electrode.
