摘　　要：采用一种电化学技术去除模拟染料废水中的甲基橙,单壁碳纳米管钛网电极作为阴阳极,考察电压、溶液pH、电解质硫酸钠质量分数等对甲基橙去除率的影响.实验结果表明,电压2 V、溶液pH值2、电解质硫酸钠1 g·L^(-1)是甲基橙去除的最优条件.甲基橙去除率可达99%以上.An electrochemical technique was used to removal methyl orange from aqueous solu- tion at a laboratory scale. The Ti net coated with single wall carbon nanotubes （SWCNTs@ Ti net） was used as both anode and cathode. Three parameters, include voltage, solution pH, and electrolyte concentration, were studied to explore the optimal condition of methyl orange removal. The re- sults showed that voltage of 2 V, solution pH value of 2 and electrolyte Na2 SO4 concentration of I g · L^-1, were the optimal parameters for methyl orange removal. The removal efficiency of methyl or- ange can reach about 99%.
