The extraction behavior of five rare earth ions (RE3+) was investigated in ionic liquid (IL) extraction system using 1-butyl-3-methyl-imidazolium hexafluorophosphate ([Bmim]PF6) ionic liquid as extraction solvent and 5,7-dichloro-8-hydroxy quinoline (HQ) as extractant.The extraction percentage of RE3+using [Bmim]PF6 was less than 8% without HQ.When sufficient HQ was included in IL phase, the extraction percentage of RE3+ could be higher than 99% except La3+.
