This paper presents study on the facilitated transport of cadmium(II), cobalt(II) and nickel(II) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) with phosphonium ionic liquid. Cyphos IL 101 (trihexyl(tetradecyl) phosphonium chloride) was used as a selective carrier for synthesis of cellulose triacetate membranes containing o-nitrophenyl pentyl ether (ONPPE) as a plasticizer. Effect of different parameters such as hydrochloric acid concentration in the source phase as well as ion carrier concentration in the polymer membrane on metal ions transport has been investigated. Cd(II) was transported preferably from hydrochloric acid solutions containing Co(II) and Ni(II) through PIM containing 18.8 wt.% CTA and 26.0 wt.% Cyphos 101 and 55.1 wt.% ONPPE into 0.5 M HNO3 as the receiving phase. The obtained results suggest that there is a possibility of application of this membrane with Cyphos IL 101 as ion carrier for separation of Cd(II) over Co(II) and Ni(II) from hydrochloric acid solutions.
