The paper deals with the influence of anode material on the efficiency of degradation for organic pollutants in water system.The electrochemical performance of fluorine ion doped lead dioxide(F--PbO2) electrode for the degradation of aniline was compared with that of undoped lead dioxide(PbO2) electrode by ultraviolet-visible(UV-Vis) spectroscopy,linear voltammetry and other analytical methods,such as the measurement by chemical oxygen demand analyzer,high performance liquid chromatography and scanning electron micrography.It was shown that both PbO2 electrode and F--PbO2 electrode could make aniline be mineralized completely and have the same degradation course,but F--PbO2 electrode has much higher electrocatalytic activity than undoped PbO2 electrode for the electrochemical degradation of aniline.The experimental results confirm that F--PbO2 electrode has much higher potential for oxygen evolution than undoped PbO2 electrode.
