摘　　要：采用低温等离子体降解水中染料活性蓝160,研究了放电功率、空气流量、溶液初始pH值、染料浓度对活性蓝160降解的影响,同时分析了其降解动力学。实验结果表明,放电功率为30 W、空气流量为56 L/h、初始pH为7.0、活性蓝160初始浓度为60 mg/L时,12 min时活性蓝160降解率最大(98.8%)。溶液初始pH为10.0时,反应动力学速率常数最大(0.94958 min-1)。一定范围内提高空气流量、放电功率、pH对活性蓝160的降解起促进作用,活性蓝160初始浓度对其降解率无明显影响。The reactive blue 160 was degraded by low temperature plasma.The effects of discharge power,air flow rate,initial pH values and dye initial concentration on the degradation of reactive blue 160 in water were studied,and the degradation kinetics was also analyzed.The experimental results showed that when the discharge time was 12 min,the input power was 30 W,the air flow was 56 L/h,the initial pH value was 7.0,and the initial concentration of reactive blue 160 was 60 mg/L,the removal rate of reactive blue 160 was the largest(98.8%).When the initial pH was changed to 10.0,the reaction rate constant was the largest(0.94958 min-1).The removal rate of reactive blue 160 increased with increasing discharge power,air flow rate and initial pH values,while the initial concentration of reactive blue 160 had no significant effect on the degradation of the reactive blue 160.
