Abstract

A novel CMPO (carbamoylmethylphosphine oxide) based task specific ionic liquid (TSIL) with an NTf(2)(-) counter anion was synthesized and evaluated for actinide/lanthanide extraction from acidic feed solutions using several room temperature ionic liquids (RTILs). The extraction data were compared with those obtained with CMPO in the same set of RTILs and also in the molecular diluent, n-dodecane. The extracted species were analyzed by the conventional slope analysis method and the extraction followed an ion-exchange mechanism. The nature of bonding in the extracted complexes was investigated by various spectroscopic techniques such as FT-IR and UV-visible spectroscopy.

摘要

合成了一种新型的基于 CMPO（羰甲基膦酸氧化物）的任务特定离子液体（TSIL），具有 NTf₂^-反离子，并使用几种室温离子液体（RTIL）评估了从酸性进料溶液中提取锕系元素/镧系元素的情况。将萃取数据与相同的一组 RTIL 以及分子稀释剂正十二烷中 CMPO 获得的数据进行了比较。通过常规斜率分析方法和萃取遵循离子交换机制对萃取的物种进行了分析。通过各种光谱技术，如傅里叶变换红外光谱（FT-IR）和紫外可见光谱（UV-visible spectroscopy）研究了萃取配合物中的键合性质。
