首次报道了使用[三辛基甲基铵][二-2-乙基己基次膦酸]([A336][P204])作为Eu(III)的n萃取剂的双功能离子液体萃取剂(Bif-ILE)在溶剂萃取中的内在协同效应，这归因于所形成的配合物具有更好的稳定性和疏水性。 [A336][P204]与Eu(III)。其他一些 Bif-ILE 也被发现具有类似的内在协同作用。本报告讨论了新型提取方案的分配系数、剥离特性和提取机制。该研究有助于获得对协同萃取和任务特定离子液体（TSIL）的新认识，此外，对其在分析化学中的潜在应用产生积极影响。
The inner synergistic effect of bifunctional ionic liquid extractant (Bif-ILE) for solvent extraction is reported for the first time using [tricaprylmethylammonium][di-2-ethylhexylphosphinate] ([A336][P204]) as n extractant for Eu(III), which can be attributed to better stability and hydrophobicity of the complex formed by [A336][P204] with Eu(III). Some other Bif-ILEs are also found to have the similar inner synergistic effect. Distribution coefficient, stripping property and extraction mechanism of the novel extraction protocol are discussed in this report. The study contributes towards acquiring a new understanding of synergistic extraction and task specific ionic liquid (TSIL), furthermore, providing a positive influence on their potential application in analytical chemistry.
