In this work the efficient transport of palladium(II) ions from hydrochloric acid solutions by transport through polymer inclusion membrane (PIM) has been studied. The membrane consisted of cellulose triacetate (CTA) as the polymeric support, o-nitrophenyl octyl ether (ONPOE) as the plasticizer and Cyanex 471X (triisobutylphosphine sulphide) as the ion carrier. The effects of various parameters on the transport kinetic and the recovery factor of palladium(II) were studied, including concentration of Cyanex 471X in the membrane, hydrochloric acid concentration in the source phase and potassium thiocyanate (KSCN) concentration in the receiving phase.
