摘要
本文综述了电离辐射技术处理水中氯酚类、氯苯类、苯胺类、染料、抗生素、重金属等污染物的研究进展;列举了降解机理、辐射源、初始浓度、初始pH值、吸收剂量、污染物去除率、矿化率等重要参数;分析了电离辐射降解污染物效率的影响因素;指出电离辐射在水处理应用中依靠产生自由基等活性粒子,而自由基本身对人体有害,需进一步研究以评估辐射技术的安全性。对电离辐射技术在污染物处理上的应用前景进行了展望。
This paper introduces the research progress of ionization radiation technology treating the chlorophenols,chlorobenzenes, anilines,dyes,antibiotics,heavy metals and other pollutants in water,enumerates the important parameters of degradation mechanism,radiation source,initial concentration,initial pH value,absorbed dose,pollutant removal rate and mineralization rate, analyzes the influence factors of ionizing radiation degradation efficiency,and points out that the application of ionizing radiation in water treatment depends on the production of free radicals and other active particles,but free radicals are harmful to human's body, which need further studies to assess the safety of radiation technology. The application prospect of ionizing radiation technology in pollutant disposal is prospected.
