英文摘要	主要考察了辛基(苯基)-N,N-二异丁基胺甲酰基甲基氧化膦(CMPO)在1-乙基-3-甲基咪唑双三氟甲基磺酰胺酸盐([C_2mim][NTf_2])中的γ辐解行为,同时考察辐射对CMPO/[C_2mim][NTf_2]萃取能力的影响。通过超高效液相色谱-四极杆飞行时间质谱联用仪(UPLC/Q-TOF-MS)进行定量分析、辐解产物认定以及产物半定量分析。CMPO/正十二烷作为对比条件进行了相同研究。结果表明:CMPO在[C_2mim][NTf_2]中的辐解率低于其在正十二烷中,并且辐解路径不同。在正十二烷体系中,CMPO主要发生C―P、C―N键的断链,而在离子液体体系中CMPO主要发生异丁基脱除...; The gamma-radiolysis of octylphenyl-(N,N-(diisobutyl)carbamoyl-methyl) phosphine oxide (CMPO) in 1-ethyl-3-methylimidazoliumbis (trifluoromethylsulfonyl) imide ([C(2)mim][NTf2]) was studied. The effect of radiation on CMPO/[C(2)mim][NTf2] extractability was also investigated. Quantitative analysis of CMPO in irradiated CMPO/ [C(2)mim][NTf2] systems, identification and semi-quantitative analysis of the radiolytic products were performed using ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS). For comparison, CMPO/dodecane was also studied under the same conditions. The radiolysis ratio of CMPO in [C(2)mim][NTf2] was found to be lower than in dodecane, because of the different radiolysis pathways. The radiolysis pathway of CMPO in molecular solvent was mainly chain scission of C-P and C-N, while that in [C(2)mim][NTf2] was the elimination of isobutyl, as well as substitution reactions with [C(2)mim](+center dot) and center dot CF3 generated from solvent [C(2)mim][NTf2]. Based on the radiolysis study, we propose a radiolysis pathway for CMPO/[C(2)mim] [NTf2], providing a deeper understanding of the radiolytic mechanism of CMPO in ionic liquids. Finally, the Eu3+ partitioning of CMPO/[C(2)mim][NTf2] from 0.01 mol.L-1 HNO3 was higher than 99% at 800 kGy.; 国家自然科学基金,湖北省2011非动力核技术协同创新计划项目资助; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); ryuuchou@sjtu.edu.cn; 08; 2101-2107; 32
