摘　　要：采用热氧化法制备了Ti/SnO2和Ti/SnO2-Sb2O3电极,以酸性品红为研究对象,对两种电极材料进行了性能比较,考察槽电压、电流密度、电解质浓度对电催化氧化处理系统的影响。结果表明:热氧化法制备出的Ti/SnO2-Sb2O3电极,其电催化性能明显优于Ti/SnO2电极;以Ti/SnO2-Sb2O3为阳极,在酸性品红初始浓度为100 mg/L、电极间距为2.5 cm、电流密度为75mA/cm2、电解质浓度取12 g Na2SO4/L时,60 min后酸性品红的去除率达到了95.41%。Ti/SnO2, Ti/SnO2 -Sb2O3 electrodes were prepared by thermal decomposition method. Using these as anodes and acid fuehsin oxidation as final aim, the electro-catalytic oxidation properties of two anodes were eompared. At the same time, the effect factors of electro-catalytic oxidation system,including tank voltage, current density and electrolyte eoneentration, was examined. The results show that the electro-catalytic ability of Ti/SnO2-Sb2O3 electrode by thermal decomposition method is markedly better than Ti/SnO2 electrode. When the initial concentration of acid fuchsin was 100 mg/L, the electrode separation was 2. 5 cm, the current density was 75 mA/cm^2 and the electrolyte concentration （ Na2SO4 ） was 4 g/L, the final removal rate of acid fuchsin by Ti/SnO2 -Sb2O3 electrode can reach 95.41% after 60 min.
