摘要

采用循环伏安法、稳态极化法等对硼掺杂金刚石薄膜电极的电化学性能及电氧化降解含环己酮模拟废水的电极过程进行了研究，考察了电流密度、支持电解质浓度、起始环己酮浓度和pH值等因素对硼掺杂金刚石薄膜电极电氧化降解含环己酮模拟废水效果的影响。实验结果表明，硼掺杂金刚石薄膜电极能够对环己酮进行有效且稳定的降解，通过正交优化实验，得到较优工艺条件为阳极电流密度为5 mA·cm-2，pH值为7，Na2SO4浓度为10 g·L-1，起始环己酮浓度为20 mmol·L-1，在该条件下COD去除率达92.95%，电流效率达80.81%，降解效果显著。

Abstract

Electrochemical performance of boron-doped diamond (BDD) film electrode and electrode process during anodic degradation of cyclohexanone on BDD film electrode were investigated by cyclic voltammetry and stead-state polarization method.The influences of current density

concentration of supporting electrolytes

initial cyclohexanone concentration and pH value on the effect of electro-degradation towards wastewater containing cyclohexanone were investigated.The result of experiments showed that cyclohexanone could be electro-degraded by BDD film electrode steadily and effectively.Through the orthogonal optimization method

the optimum conditions were obtained as follows: anodic current density 5 mA·cm-2;pH value 7;concentration of supporting electrolyte（Na2SO4）10 g·L-1;initial concentration of cyclohexanone 20 mmol·L-1.Under these conditions

the removal of COD was 92.95% and current efficiency was 80.81%.The effect of degradation was excellent.
