摘要

利用,60,Co γ射线（2.2—14.9kGy）辐照4-氯酚水溶液，研究了其辐照降解特性。通过对辐照前后4-氯酚的紫外可见光谱、有机氯脱除率、化学需氧量（Chemical oxygen demand, COD）去除率的研究，探讨了吸收剂量、H,2,O,2,加入量、初始浓度、溶液pH值对降解效果的影响。结果表明，这一辐射技术能有效降解4-氯酚，有机氯脱除率可达100%，COD去除率可达65.8%。

Abstract

Degradation of 4-chlorophenol in aqueous solutions has been studied by γ-ray irradiation of 2.2−14.9kGy. Absorption spectra, chemical oxygen demand (COD) and Cl removal efficiency of the sample solutions were investigated under different irradiation conditions. COD removal efficiency and the Cl removal efficiency could be 65.8% and 100%, respectively. In addition, the results show that H,2,O,2, plays an important role in the radiolysis degradation of 4-chlorophenol. It is concluded that the irradiation technology is an effective method for treatment of waste effluents with chlorophenol.
