摘    要:文章研究了影响Fenton试剂氧化降解持久性有机污染物直接耐晒黑G的因素,如光源的选择、初始pH值、H2O2的用量、Fe2 的用量、阳离子交换树脂载体的引入等,通过研究确定了各因素的优化条件.研究结果表明:太阳光照能有效的促进直接耐晒黑G染料的降解脱色,大大缩短反应时间;引入阳离子交换树脂后,可增强Fenton氧化反应的活性,降解效果更好.

关 键 词:光助Fenton试剂  直接耐晒黑G  持久性有机污染物  降解  脱色

Abstract:Photo-Fenton reagent can degradate dye well.In the present paper,some main factors such as different light sources,the initial pH value,the dosage of Fe~(2 ) and H_2O_2,the cation-exchange resin,etc.,which have great influences on degradation,were researched.Through numerous experiments,the optimum condition for dye direct fast light black G degradation was given.The results of the research were as follows: the sunlight can promote this reaction apparently,and the reaction time can greatly be shortened;Under optimal conditions,after the cation-exchange resin was introduced into the Fenton system,the activation of Fenton reagent for degradation reaction was enhanced to a great extent,the degradation effect of direct fast light black G was better,and the ratio of color removal was more than 94% within 40 min.
Keywords:Photo-Fenton reagent  Direct fast light black G  Persistent organic pollutant  Degradation  Color removal
