Abstract

The anodic discharge of water to produce adsorbed hydroxyl free radicals (· OH) is considered to be a prerequisite to anodic O-transfer reactions at a PbO₂ electrode. In this work, a method was studied by means of high-performance liquid chromatography (HPLC) combined with electrochemical detection (ED) so as to investigate the production of hydroxyl free radicals (· OH) in the process of the anodic discharge of H₂O at a PbO₂ electrode. The voltammetric data obtained at the PbO₂ electrode for the oxidation of salicylic acid to salicylate hydroxylation products (DHBAs) and the detection of DHBAs by means of HPLC-ED confirm the proposed mechanism.
