The electrode materials were characterized by a scanning electron microscope(SEM), X-ray diffraction(XRD) and cyclic voltammetry(CV) measurements. The electro-catalytic activity for degradation of sulfisoxazole(SIZ) was investigated by using prepared graphene or graphite anode. The results showed that the degradation of SIZ was much more rapid on the graphene than that on the graphite electrode. Moreover, the graphene electrode exhibited good stability and recyclability. The analysis on the intermediate products and the measurement of active species during the SIZ degradation demonstrated that indirect oxidation is the dominant mechanism, involving the electro-catalytic generation of OH and O_2^- as the main active oxygen species. This study implies that graphene is a promising potential electrode material for long-term application to electro-catalytic degradation of organic pollutants. 关键词：电催化降解石墨阳极异恶唑磺胺循环伏安法电极材料 X-射线衍射石墨电极
