摘　　要：以活性红3BS染料为研究对象,采用光活化过硫酸钾技术(UV/K_(2)S_(2)O_(8))对活性红3BS进行降解可行性研究,结果表明活性红3BS在UV/K_(2)S_(2)O_(8)体系下具有较好的降解效果.采用单因素变量法和响应曲面法探究底物初始浓度、pH值和K_(2)S_(2)O_(8)质量浓度对降解动力学的影响,得出活性红3BS染料的降解最佳反应条件是底物浓度为162.50μmol·L^(-1),pH值为3.0,K_(2)S_(2)O_(8)质量浓度为1.75 g·L^(-1),反应时间60 min,其降解率为95.5%,COD去除率为37.4%.Taking reactive red 3BS dye as the research target,the photo-activated potassium persulfate technology(UV/K_(2)S_(2)O_(8))is used to degrade the feasibility of reactive red 3BS.The results show that reactive red 3BS can be degraded efficiently under the UV/K_(2)S_(2)O_(8)system.Then,the effects of initial substrate concentration,pH value and the concentration of K_(2)S_(2)O_(8)on the degradation kinetics are investigated by single-factor variable method and response surface method.The optimum reaction conditions are obtained as following,the reactive red 3BS dye with a substrate concentration of 162.50μmol·L^(-1),pH value of 3.0,the concentration of K_(2)S_(2)O_(8)of 1.75 g·L^(-1),reaction time of 60 min.Under the optimum reaction conditions,the degradation rate of reactive red 3BS is 95.5%,and the COD removal rate can be achieved as 37.4%.
