摘要
三价镧系元素和次锕系元素的分离是核工业中乏燃料处理的关键。为实现两者的有效分离,通过合理的配体结构设计从而选择性的络合一种金属进而达到分离的目的是当前液-液萃取配体设计的通用策略。其中,高效水溶性配体的设计能够极大程度的降低液-液萃取过程中有机溶剂的使用进而备受关注。本文简要的梳理了近10年来水溶性配体的发展,根据致溶基团将水溶性镧锕分离配体分为三个部分并讨论了不同结构配体的优缺点。最后结合我们课题组的近期工作进展对水溶性配体的发展方向进行了展望。
The separation of trivalent lanthanides and minor actinides(Lns/Ans)is critical for spent fuel processing in the nuclear industry.Delicate design of highly selective ligand is the most common strategy used in liquid-liquid extraction process to achieve this goal,in which,the design of highly efficient water-soluble ligands can greatly reduce the use of organic solvents and has attracted much attention.In current contribution,we briefly summarized the development of hydrophilic Lns/Ans separation ligands in the past decade by dividing the ligands into three parts according to the solubilizing groups.For each part,the representative ligands were introduced and both pros and cons of each group of ligands was discussed.Finally,based on our understanding and the current work in our group,the future development of hydrophilic Lns/Ans separation ligands is prospected.
