    The extractions of U(VI) from nitric acid medium by tri-n-butylphosphate (TBP) dissolved in non-traditional diluent, namely 1-octyl-3-methylimidazolium hexafluorophosphate ([C8mim][PF6]) and 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) ionic liquid (IL), were studied. The experimental results indicated that, TBP/[C8mim][PF6] demonstrated more performance for extracting uranium than TBP/[C4mim][PF6], due to the better hydrophobicity of [C8mim][PF6]. The distribution ratio for the extraction of U(VI) from nitric acid by TBP/IL was increased with gaining nitric acid concentration. Furthermore, the extraction of strontium using t-BAMBP(4-tert-butyl-2-(α-methylbenzyl) phenol) as extractant instead of crown ethers was also studied in this paper. The preliminary results showed that the better extraction efficiency values (ESr2+∼94.26%) can be achieved using [C4mim][PF6] as diluent. (authors)
