Synthesis, characterization and development of ion imprinted technique for designing a nickel ion selective membrane

A nickel (II) imprinted membrane with a porous polyvinylidene fluoride (PVDF) membrane as a supporting substrate was prepared by surface ionic imprinting technology.These materials can be prepared by polymerization of functional and cross-linking monomers around a template molecule (target). The effect of imprinting technique on the selective recognition of Ni (II) ion towards Co (II) ions through the modified imprinted membrane was studied in the permeationexperiments. The separation factor ( ) of the imprinted membrane for the Ni2+ ion versus Co2+ ions was 2.6, whereas the non-imprinted and control membrane did not show any selectivity
