A supported liquid membrane (SLM) system for the selective separation of platinum(IV) from palladium(II) has been developed. The SLM was prepared using imidazolium-based IL 1-octy-3-methylimidazolium bis(trifluoromethanesulfonyl)- imide. The initial flux and separation factor of Pt(IV) from Pd(II) were found to significantly depend on the composition of the receiving solution. Based on the performance, a 0.1 mol dm-3 NaClO4 solution was selected as a suitable receiving solution. Membrane transport experiments showed that 93% of Pt(IV) can be selectively transported into the receiving solution, whereas most Pd(II) remains in the feed solution.
