The extraction behavior of scandium ion (Sc3+) was investigated using 1-butyl-3-methyl -imidazolium hexafluorophosphate ([Bmim]PF) ionic liquid as extraction solvent and 2-ethylhexyl phosphonic acid-2-ethylhexyl ester (P507, HA) as extractant. The extractablity of Sc3+ using [Bmim]PF was less than 5% without P507. When the initial P507 concentration in IL phase was 0.2 mol/L, percentage extraction of 5×10-5 mol·L-1 Sc3+ exceeded 99%. The results showed that the extracted species in the Sc3+­-P507-[Bmim]PF6 system was neutral ScA3 and [Bmim]PF6 solvent could be used repeatedly.
