英文摘要	Room-temperature ionic liquids (RTILs), especially those containing imidazolium cations, for instance 1,3-dialkylimidazolium, associated with various inorganic anions are receiving an ever-increasing amount of interest as environmentally benign alternatives to volatile organic solvents for traditional liquid-liquid extraction of high level radioactive nuclides in nuclear fuel reprocessing, because of their low volatility, good thermal and chemical stability, as well as excellent extraction capacity. The application of RTILs in nuclear fuel reprocessing, however, requires a comprehensive knowledge of radiation effects on RTILs and their extraction systems. Herein, we reviewed our recent investigations of gamma-radiation effects on two widely used hydrophobic RTILs [C(4)min] X and [C(4)min] X-based extraction systems, where [C(4)min] (+) is 1-butyl-3-methylimidazolium and X is hexafluorophosphate (PF(6)(-)) and bis (trifluoromethylsulfonyl) imide ([NTf(2)] (-)), respectively. The investigations involved radiation effects on chemical structure and some properties, especially phase behavior and fluorescence properties of neat RTILs under nitrogen atmosphere and of RTILs in the presence of nitric acid, separation and analysis of radiolytic products of RTILs, and influence of gamma-irradiation on RTILs-based extraction systems during extraction of metal ions. Based on the results, the feasibility of RTILs as alternative media for the separations of high level radioactive nuclides from spent nuclear fuel was evaluated, and further studies on the radiation effects on RTILs and RTILs-based extraction system are prospected.; Chemistry, Multidisciplinary; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 0; ARTICLE; 7,SI; 1469-1477; 23
