摘要：

In this work, a separation and purification process of U(VI), Zr(IV) and I-2 from various fission products in nitric acid solution by 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C(4)mim][NTf2]) and dibutyl-3-(3-methylimidazolium)propylphosphoramide bis(trifluoromethanesulfonyl)imide-task specific ionic liquid (phosphoramide-TSIL) was investigated. The phosphoramide-TSIL was found to reduce ligand loss compared to dibutyl propylphosphoramidate by total organic carbon testing (TOC). The stripping of U(VI), Zr(IV) and I-2 could be achieved by guanidine carbonate solution, oxalic acid solution and sodium hydroxide solution, respectively. The phosphoramide-TSIL/[C(4)mim][NTf2] showed good irradiation stability and recyclability. Phosphoramide-TSIL has the potential to be applied for separation and purification in the actual radioactive environment. [GRAPHICS] .
