| 中文摘要 | 研究了利用60Co-γ源辐照降解4-氯酚的过程,探讨了辐照剂量、溶液的初始pH值、初始浓度、不同气体条件以及自由基清除剂等因素对4-氯酚辐照降解的影响。采用高效液相色谱仪(HPLC)、总有机碳(TOC)分析仪、离子色谱仪(IC)、可吸附性有机卤化物(AOX)分析仪及紫外分光光度计等测试手段评价了4-氯酚在不同实验条件下的辐照降解效果。实验结果表明,较低的4-氯酚初始浓度,较高的辐照剂量及低pH值能够提高其降解速率。提高正丁醇的质量浓度可减少4-氯酚的降解率,说明自由基清除剂对4-氯酚的辐照降解有明显的抑制作用。; The radiation-induced degradation of 4-chlorophenol (4-CP) in an aqueous solution by ~ 60 Co-γ radiation technology is a function of the irradiation dose, the initial 4-CP concentration, the pH value, and free radical scavengers. The degradation of 4-CP was analyzed by measuring the absorption spectra, chloride ion release, total organic carbon (TOC), and adsorbable organic halogens (AOX). The results show that lower initial 4-CP concentrations, higher radiation doses, and lower pH increase the 4-CP degradation. The 4-CP degradation effciency decreased with increasing n-butanol concentration indicacting that ·OH scavengers significantly influence the degradation of 4-CP by gamma rays.; 国家自然科学基金资助项目(50325824); 教育部优秀青年教师计划项目 |
