The decomposition of humic acid on the Pt/Ti and SnO2/Ti electrodes was investigated by measuring the total organic carbon (TOC) and UV-visible spectrum. The results showed that humic acid could be decomposed electrochemically and the efficiency in the decomposition of humic acid on the SnO2/Ti electrode was higher than that on the Pt/Ti electrode. The effects of different types of supporting electrolyte, their concentrations and the initial concentration of humic acid on the electrochemical decomposition of humic acid were investigated. Na2SO4 was found to be a suitable supporting electrolyte and the decomposition of humic acid was achieved efficiently at low electrolyte concentration.
