Abstract: The electrochemical oxidation reaction of organic pollutant aniline on catalytic electrodes is studied through cyclic voltammetry and anodic polarization curves of the catalytic electrodes measured in different intermedia.The results showed that there were two degradation ways of electrocatalytic oxidation of aniline in different electrodes and variant reaction intermedia,which are co\|oxidation and indirect oxidation.The degradation process and efficiency are influenced by factors such as the intermedia of the solution,the electrocatalytic activities and oxygen evolution voltage of the electrode.
