摘要

苯胺及其衍生物是一类主要的环境污染物，许多已被我国及欧洲国家列为优先污染物,[1,2],。本工作研究了苯胺、对硝基苯胺和间氯苯胺水溶液的电子束辐照降解过程。三种溶液初始浓度均为0.5mmol/L，其辐照前后稀释五倍的紫外可见吸收光谱表明，苯胺在230nm的吸收峰，对硝基苯胺在380nm的吸收峰，以及间氯苯胺在236nm的吸收峰，均随辐照吸收剂量的增加而逐渐降低。辐照吸收剂量为23kGy时，分别降低为初始吸光度的42.8%、4.3%和27.7%。表明电子束辐照能够较为有效的破坏苯胺、对硝基苯胺和间氯苯胺的分子结构，使其得到降解。

Abstract

The degradation of aniline,p,-nitroaniline and ,m,-chloroaniline by electron beam irradiation was studied. Removal of aniline,p,-nitroaniline and ,m,-chloroaniline reached 95% at an initial concentration of 0.5mmol/L at 23kGy. The results showed that electron beam irradiation is an effective process for the degradation of aniline and its derivatives.
