| 英文摘要 | The application of room-temperature ionic liquids (RTILs) in nuclear spent fuel recycling requires a comprehensive knowledge of radiation effects on RTILs. Although preliminary studies indicate a relatively high radiation stability of RTILs, little attention is paid to the color change of RTILs, an obvious phenomenon of RTILs during irradiation. In this paper, we have investigated radiation-induced darkening and decoloration of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ([BMIm][NTf2]), an ionic liquid representing the most popular class of RTILs, by means of UV-Vis analysis and time-dependent density functional theory calculations. Based on the experimental and computational results, it is proposed that the color change of [BMIm][NTf2] upon irradiation originates from the formation of double bonds in the aliphatic chains of pristine organic cations (or radiolytic products of RTILs) and various associated species containing these "doublebond products''. This work sheds light on the understanding of the radiation-induced color change of RTILs. |
