摘　　要：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.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.
