The electrochemical oxidation of salicylic acid (SA), salicylaldehyde (SH), and their mixtures at Ti/IrO2-SnO2-Sb2O5 electrodes was studied using in situ UV/vis spectroscopy. Plackett-Burman's experimental design was employed to simultaneously investigate the effect of current density, temperature, mass transfer, composition of the electrode materials, initial concentration, and supporting electrolyte on the electrochemical oxidation of SA, revealing that temperature and the applied current density are the two major factors. The kinetics of the electrochemical oxidation of SA and SH was thus investigated at different temperatures and current densities, showing that the electrochemical oxidation of SA and SH is governed by the hydroxyl radical reaction and follows first-order kinetics with the apparent activation energy of 24.8 and 17.2 kJ/mol, respectively. The competitive effects of SA and SH during the electrochemical oxidation of their mixtures were further studied using UV/vis spectroscopy and multivariate calibration.
