1-methyl-3-octylimidazolium saccharinate {[C₈C₁im][Sac]} – a hydrophobic but polar ionic liquid (IL) capable of capturing and liberating water in a controllable manner was employed as an extraction phase in the liquid–liquid extraction for the recovery of radioactive elements (²⁴¹Am, ¹³⁷Cs and ⁶⁰Co) from aqueous solutions. The influence of factors such as IL/aqueous source ratio, pH and presence of complex-forming agents (citric acid, oxalic acid) on the extraction yield was comprehensively studied. The radionuclides were shown to possess different behavior under the same conditions, the latter being attributed, and further proved by theoretical speciation analysis, to the formation of species capable of interacting in a specific manner with the IL-phase. The results obtained showed the possibility for controllable and selective transfer between the IL and aqueous phases and resulted in the development of a simple procedure for extraction and concentration of ²⁴¹Am. The method developed proved successful in the monitoring of this radionuclide in drinking water samples.

1-甲基-3-辛基咪唑糖精{{C ₈ C ₁ im] [Sac]} –一种能够以可控方式捕获和释放水的疏水性但极性离子液体（IL）被用作液体中的萃取相–液体萃取以回收放射性元素（²⁴¹ Am，¹³⁷ Cs和⁶⁰Co）从水溶液中提取。全面研究了IL /水源比，pH和络合剂（柠檬酸，草酸）的存在对提取率的影响。放射性核素在相同条件下表现出不同的行为，后者归因于并形成了能够通过特定形态与IL相相互作用的物种形成，并通过理论形态分析进一步证明了这一点。获得的结果表明，IL和水相之间可控和选择性转移的可能性，并导致了提取和浓缩²⁴¹ Am的简单程序的发展。事实证明，所开发的方法在监测饮用水样品中的这种放射性核素方面是成功的。
