Diffusive transport of Cu(II) ions through thin ion imprinted polymeric membranes

A novel ion imprinted polymeric membrane (IIPM) for copper (Cu) ions transport was prepared by a ion imprinting technique via cross-linking of blended chitosan (CS)/polyvinyl alcohol (PVA) using glutaraldehyde (GA) as the cross-linker and Cu ions as the template. The obtained IIPM was characterised...

Description
Summary:A novel ion imprinted polymeric membrane (IIPM) for copper (Cu) ions transport was prepared by a ion imprinting technique via cross-linking of blended chitosan (CS)/polyvinyl alcohol (PVA) using glutaraldehyde (GA) as the cross-linker and Cu ions as the template. The obtained IIPM was characterised and evaluated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and permeation studies. Cavities of IIPM containing recognition sites for Cu ions were formed in the compact structure of the CS/PVA membrane which was prepared via the solution casting method. Under the optimum conditions, transport factor of the IIPM reached 2 when the permeation time was 18 h. Selective permeation of Cu ions versus nickel ions through the imprinted membrane was confirmed and a selectivity factor of 1.71 was obtained.
