摘要：
The trace water-soluble radiolytic products of neat 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)-imide ([C(4)mim][NTf2]) were identified by analysing water-washed samples of.-ray irradiated ionic liquids. CF3SO2OH, CF3SOOH, CF3SO2NH2, HF and H2SO3 were confirmed as main radiolytic products of [C(4)mim][NTf2], and the total radiation chemical yields of the water-soluble radiolytic products (0.35 mu mol J(-1)) and that of hydrogen ions (0.46 +/- 0.02 mu mol J(-1)) were determined by using ion chromatography and neutralization titration, respectively. It was found that the water-soluble radiolytic products of [C(4)mim][NTf2] greatly reduced the extraction efficiency of Sr2+ from water to irradiated [C(4)mim][NTf2], while the waterinsoluble radiolytic products of [C(4)mim][NTf2] had a slight influence on the Sr2+ extraction.
