英文摘要	College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China (Received May 19, 2014; accepted in revised form June 23, 2014; published online December 20, 2014) The water-soluble radiolytic products of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid ([C_2mim][NTf_2]) under r-radiation, such as CF_3SOOH, CF_3SO_2NH_2, HF, and H_2SO_3, were identified by using ~1H NMR, ~(19)F NMR, and ion chromatography. The extraction behavior of Dy~(3+) using irradiated [C_2mim][NTf_2] in combination with 2,6-di(5,6-diisobutyl-1,2,4-triazin-3-yl)pyridine (isobutyl-BTP) was studied and the abnormal increase of Dy~(3+) partitioning after irradiation is mainly attributed to the precipitation formed between Dy~(3+) and radiolytic products of [C_2mim][NTf_2] (F~– and SO_3~(2–)). Washing irradiated [C_2mim][NTf_2] with water provides a simple method for ionic liquid recycling.; the Program for Professor of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning,the National Natural Science Foundation of China,Supported by the Ph.D. Programs Foundation of Ministry of Education of China; 中国科学引文数据库(CSCD); 1; S10306-1-S10306-5; 26
