The characteristic of electrochemical degradation of aniline on SnO2/T i anode have been studied.The results indicate that SnO2/Ti anode doped with F plays an obvious role of electrocatalysis on the degradation of aniline differen t from that on Pt anode.The kinetics factors that influent the oxidation rates o f aniline on SnO2/Ti anode are determined by the dissolving of intermediate prod ucts on anodes.The dissolving of the organic film with intermediate products on the anode is the rate determining step.The effects of aniline concentration,pH o f aniline solution and the current density on the rate of aniline degradation ha s been studied.Under the best condition,the most efficient rate of elimination o f aniline(99.1％) and current efficiency (99.8％) could be achieved.The complexi ty of the intermediate products,the basic cate ry of the intermediate products consiste of the black film have been analyzed.
