| 摘 要： | 氯苯类是重要的有机污染物,采用常规处理方法难以降解。利用束流为1mA、电子束能量为1 5MeV的高能电子束辐照处理氯苯、邻,间,对 二氯苯、1,2,4 三氯苯5种氯苯类化合物的模拟废水。辐照剂量分别为35、70、105、140、210kGy。实验表明,电子束能够降解氯苯类废水,邻二氯苯、间二氯苯、对二氯苯、氯苯降解率为50%时所需剂量分别为:38、35、46、206kGy。相同剂量下各化合物的降解率顺序为:氯苯<二氯苯<1,2,4 三氯苯,辐照降解过程中氯离子的质量浓度增加,辐照后溶液呈强酸性,pH=2～3。

| Abstract: | Chlorobenzenes are a kind of organic contaminants which are difficult to be decomposed by normal methods.Decomposition of five organic compounds including chlorobenzene ,o-,m-,p-dichlorobenzene and trichlorobenzene with electron beam(current:1 mA,energy:1.5 MeV) were studied.Radiation doses of the electron beam were 35,70,105,140,210 kGy respectively.The results show that chlorobenzenes can be decomposed efficiently with electron beam.At the same dose,the decomposition rates of the chlorobenezenes are as follows:chlorobenzene
