Abstract: Transition Metal ion imprinted interpenetrating polymer networks were synthesized for selective removal of Fe(III), Co(II), Ni(II), Cu(II) ions from water. The polymers were prepared using template metal ions such as Fe(III), Co(II), Ni(II), Cu(II) ions a biopolymer alginic acid and N,N' Methylene-bis-acrylamide (NNMBA) crosslinked polyacrylamide using potassium persulphate as initiator. The non-imprinted polymer networks were also prepared without use of the metal ions. To determine the selectivity of ion imprinted polymers, competitive sorption studies were carried out and proved that ion imprinted polymers (IIP) showed good selectivity for the target metal ion and can be applied for water remediation.
