摘　　要：文章借助循环伏安法（CV）研究了邻二苯酚（CAT）在碳纳米管修饰玻碳电极（CNTs/GCE）表面的电催化氧化行为。试验结果表明：CNTs/GCE对邻二苯酚的氧化过程表现出良好的催化活性,其响应峰电流与裸GCE相比增加了10倍以上;在最佳响应条件下,在0.25~2.0 mmol/L的浓度范围内,邻苯二酚的催化氧化峰电流与浓度呈良好的线性关系;并对模拟废水中的邻苯二酚进行了回收试验。Carbon nanotubes （CNTs） were loaded on the glassy carbon electrode to prepare carbon nanotube modified glassy carbon electrode （CNTs/GCE）. And the electrocatalytic oxidation behavior of catechol was investigated on this modified electrode by cyclic voltammetry （CV） of the electrochemical methods. Results show that good electrocatalytic activity for catechol oxidation could be observed at CNTs/GCE. Compared with bare GCE, the response peak current of CNTs/GCE had an increase of more than 10times. Under the optimal condition of response, the oxidation peak current were increased linear with the concentrations of catechol at the range 0.25 -2.0 mmol/L. And the recovery test of catechol in simulating wastewater was satisfactory.
