Hydrophobic ionic liquids are promising extraction media in solvent extraction separation of metal ions[l].In this work, the extraction behavior of several rare-earth metals (Y, Nd, Eu, Dy) from nitric acid solution was studied using an novel extracting system based on hydrophobic ionic liquid.The novel extracting system is made up of 2,6-bis(5,6-dibutyl-l,2,4-triazin-3-yl) pyridine (isoBu-BTP),which acted as extractant, can separate lanthanides and minor actinides effectively in nitric acid solution, and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C2 mim][NTf2]),which acted as extraction medium, shows a great solubility against isoBu-BTP [2].
