Laboratory experiments were carried out on the kinetics and pathways of the electrochemical (EC) degradation of phenol at three different types of anodes, Ti/SnO₂-Sb, Ti/RuO₂, and Pt. Although phenol was oxidised by all of the anodes at a current density of 20mA/cm² or a cell voltage of 4.6V, there was a considerable difference between the three anode types in the effectiveness and performance of EC organic degradation. Phenol was readily mineralized at the Ti/SnO₂-Sb anode, but its degradation was much slower at the Ti/RuO₂ and Pt anodes. The analytical results of high-performance liquid chromatography (HPLC) and gas chromatography coupled with mass spectrometry (GC/MS) indicated that the intermediate products of EC phenol degradation, including benzoquinone and organic acids, were subsequently oxidised rapidly by the Ti/SnO₂-Sb anode, but accumulated in the cells of Ti/RuO₂ and Pt.
