| 摘 要： | 采用大气压介质阻挡放电等离子体技术,对4-氯酚(4-CP)水溶液进行了降解处理,研究了放电参数对4-CP降解效率以及过氧化氢产生量的影响,并对降解动力学进行了分析。结果表明,当电源电压为160 V、电流为0.5 A、介质间距为5 mm时,4-CP的降解效果最好;随着电压、电流的提高,间距的减小,过氧化氢的生成量增加;Fe2+对4-CP的去除有明显的催化作用。动力学研究表明,4-CP的质量浓度低于200 mg·L-1时降解为1级反应,高于400mg·L-1时为0级反应。

| Abstract: | In the present study,effects of discharge parameters on degradation of 4-Chlorophenol(4-CP) and formation of hydrogen peroxide(H2O2) induced by dielectric barrier discharge were investigated.Kinetics of 4-CP was also discussed.The results show that the effect of 4-CP degradation is best at the voltage of 160 V,electric current of 0.5 A,and the air gap distance of 5 mm.The formation of H2O2 increased with increasing the voltage and current,decreasing the air gap distance.It is also demonstrated that ferrous ... |
