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 UO22+, La3+ or Th4+ exhibited different effects on the system. It was found that small amount of UO22+ 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 UO22+. Different factors were further studied to optimize the separation efficiency of the extraction-precipitation process.
