ABSTRACT
The removal of iron(III) from chloride acidic aqueous solutions in solvent extraction and transport through polymer inclusion membranes (PIMs) has been studied. D2EHPA was used as the extractant/ion carrier in these processes. The extraction of Fe(III), Mn(II), Ni(II), Cu(II) and Co(II) with 0.5 M D2EHPA was: 73.4 %, 11.2 %, 15.3 %, 7.8 % and 23.9 %, respectively. Separation factors (S) for metal ions were calculated and reported. The transport across PIM containing cellulose triacatate (CTA) as the support and o-nitrophenyl octylether (ONPOE) as the plasticizer was found to be the effective and selective method of Fe(III) ions removal from aqueous chloride solutions containing Mn(II), Ni(II), Cu(II) and Co(II) ions. The stability of PIMs was also studied. Present studies indicate that the transport across PIM has the long term integrity.
