| 摘 要： | 支撑液膜（SLM）发展迅速、应用前景广阔，在众多支撑液膜性能改进的研究中，采用离子液体（IL）代替传统有机溶剂，已在气体、有机物分离以及生物反应器方面有一定的进展。本实验采用疏水性聚丙烯中空纤维（HF）作支撑体，针对目标金属Cs离子选择杯冠化合物DB18C6作萃取剂，预选Bmim]PR]、Bmim]NTf2]和Bmim]BF4]三种ILs作稀释剂制备膜体系，探索其在Cs／Mo分离中的应用潜力。结果表明，在本实验工艺条件下，使用Bmim]PF6]成功制备了离子液体中空纤维支撑液膜体系（IL—HFSLM），该液膜体系在料液流速低于5mL／min的条件下稳定存在，并可实现从含Mo溶液中回收超过80％的Cs。
