摘　　要：制备了不同Al掺杂量的Al-PbO_(2)/TiO_(2)纳米管电极,将最优的电极应用于阳极电催化氧化三氯生废水,并进行条件优化。结果表明,Al掺杂摩尔分数为1.0%的Al-PbO_(2)/TiO_(2)纳米管电极在电解质Na 2SO 4摩尔浓度为0.15 mol/L、电流密度为25 mA/cm 2、初始pH=3的条件下,电解120 min后,可以获得最大的三氯生(200 mL、10 mg/L)去除率(100.00%),并且通过一级动力学模型拟合发现,此时反应速率也快。The Al-PbO_(2)/TiO_(2) nanotube electrodes with different Al-doped amount were prepared,the best electrode was applied to anodic electrocatalytic oxidation of triclosan(TCS)in water,and the conditions were optimized.Results showed that the Al-PbO_(2)/TiO_(2) nanotube electrode with Al-doped molar ratio of 1.0%achieved the highest removal rate(100.00%)for TCS(200 mL,10 mg/L)when sodium sulfate electrolyte was 0.15 mol/L,the current density was 25 mA/cm 2,and initial pH=3 after 120 min electrolysis.And it was found that the reaction rate was fast under the optimized conditions by the first-order kinetic model fitting.
