【摘要】 三氯苯是重要的有机污染物,采用常规处理方法难以降解。利用电子束对1,2,4-三氯苯水溶液进行辐照降解处理,结果表明电子束辐照可以有效降解三氯苯,对于200mg/L 的三氯苯水溶液在辐照剂量达到105kGy 时去除率可达到100%,辐解后溶液呈酸性。添加剂H2O2对三氯苯的辐解有抑制作用。通过对实验过程的分析,给出了1,2,4-三氯苯的辐照降解机理。更多还原

【Abstract】 In this paper the decomposition of 1,2,4-trichlorobenzene by electron beam was studied. The results show that electron beam processing is an effective way to decompose trichlorobenzene, 200mg/L trichlorobenzene solution can be completely decomposed at 105kGy irradiation dose. The pH of the solution decreased to 2-3 after irradiation. The addition of H2O2 slow down the decomposition rates of 1,2,4-trichlorobenzene. The decomposition mechanism of 1,2,4-trichlorobenzene is analyzed based on experimental results.更多还原
