摘要:

离子液体(ILs)具有低挥发性和化学稳定性,在萃取金属离子方面有着优异的表现,被认为是乏燃料后处理中的新一代绿色溶剂. 然而在萃取放射性核素过程中,离子液体将处于强辐射场,因此离子液体辐射效应研究是其实际应用的前提. 本文综述了国内外关于离子液体的辐射效应研究进展,包括辐照对离子液体结构和性质的影响,离子液体的脉冲辐解和激光光解研究,离子液体辐解产物的分析及其对核素萃取的影响等研究进展,并对今后该领域的研究方向进行了展望.

关键词: 离子液体, 辐射效应, 萃取, 辐解产物, 乏燃料后处理

Abstract:

Ionic liquids (ILs) are regarded as a new generation of green solvents in spent nuclear fuel reprocessing, because of their fascinating properties such as negligible vapor pressure, high thermal stability, and successful use in the extraction of metal ions. However, the full realization of their potential requires a comprehensive knowledge of radiation effects on ILs, as they would be exposed to high radiation dose during extraction of high-level radioactive nuclides. This review presents research on the radiation effects on ILs, including radiation effects on the structures and properties of ILs, pulse radiolysis and laser photolysis of ILs, identification of radiolytic products of ILs and their influence on the extraction of metal ions. Our vision for the further development of this field is also proposed.

Key words: Ionic liquid, Radiation effect, Extraction, Radiolytic product, Spent nuclear fuel reprocessing
