Abstract In this work, a novel task specific ionic liquid (TSIL) [tributyl(hexyl)phosphonium]2[diglycolic acetate] ([P6,4,4,4]2[DGA]) was prepared and used to construct a vesicle system. The addition of UO2 2+, La3+ or Th4+ exhibited different effects on the system. It was found that small amount of UO2 2+ could induce large-sized aggregation of vesicles and make the precipitation happen, while La3+ and Th4+ did not have such capacity. The whole process was characterized by dynamic light scattering and freeze-fracture transmission electron microscopy. An extraction-precipitation strategy was then developed for the selective recovery of UO2 2+. Different factors were further studied to optimize the separation efficiency of the extraction-precipitation process.

UO22+诱导离子液体超分子组装：一种选择性萃取-沉淀策略

摘要 在这项工作中，制备了一种新型任务特异性离子液体 (TSIL) [三丁基（己基）鏻]2[二甘醇乙酸酯]（[P6,4,4,4]2[DGA]）并用于构建囊泡系统。 . UO2 2+、La3+或Th4+的加入对体系表现出不同的影响。发现少量的UO2 2+ 可以引起囊泡的大尺寸聚集并发生沉淀，而La3+和Th4+则没有这种能力。整个过程通过动态光散射和冷冻断裂透射电子显微镜进行表征。然后开发了萃取-沉淀策略以选择性回收 UO2 2+。进一步研究了不同的因素以优化萃取-沉淀过程的分离效率。
