[Comparative Study of Benzotriazole Electrochemical Oxidation at Boron-doped Diamond and PbO2 Anodes].
Huan Jing Ke Xue. 2015 Jul; 36(7):2540-6.HJ

Abstract

Electrochemical systems were built to investigate the degradation of benzotriazole (BTA) on boron-doped diamond (BUU) and PbO2 anodes and give an insight into the mineralization ability of two electrodes in terms of the amount and activity of hydroxyl radicals. Results of bulk electrolysis showed that both BDD and PbO2 displayed perfect BTA degradation performance after 12 hours' electrolysis, with the removal percentages of 99. 48% and 98. 36%, respectively, while the mineralization ability of BDD was much stronger than that of PbO2, with the efficiency of 87. 69% for BDD and 35. 96% for PbO2. Less hydroxyl radical and hydrogen production in BDD system suggested the less amount of active sites on BDD surface, thus further verified that the generated hydroxyl radical amount was not the primary factor determining the mineralization ability of anodes. However, BDD displayed larger binding energy of adsorbed oxygen and thinner adsorption layer than those of PbO2, indicating that the BDD electrode surface was of greater catalytic activity, thus the generated hydroxyl radicals were more free, which was the key to its better mineralization ability.
