Abstract

Molecularly imprinted polymer membranes for selectively collecting phosphate, nitrate and ferric ions are disclosed, prepared by copolymerizing a matrix monomer, cross-linking agent, ion imprinting complex, permeability agent and polymerization initiator, after which the ions of the ion imprinting complex are permeability agent are removed. The permeability agent creates channels in the membrane permitting the ion binding sites in the membrane to communicate with the exterior surface of the membrane.
