Synthesis and characterization of Fe(III)-ion imprinted polymer for recovery of Fe(III) from water samples
Year: 2010
Type: article
Abstract: Ion imprinted polymer (IIP) was prepared by formation of binary complex of iron (imprint ion) with acrylic acid (functional monomer) in cyclohexanol and thermally copolymerizing with styrene (monomer) and divinylbenzene (crosslinker) in presence of 2, 2'-azobisisobutyronitrile (AIBN) as initiator. Imprinted Fe(III) was completely removed by leaching IIP with 1 M HNO 3 and characterized by FTIR and surface area measurement. Cation exchange capacity (H + /Na + ) of IIP was 0.249 mmol g -1 . Adsorption equilibrium time was found to be 60 min. Maximum adsorption (62.4 mg g -1 ) of Fe(III) ions on to IIP was at pH 6. Distribution studies showed selectivity order as: Fe(III) > Zn(II) > Co(II) > Ni(II). Fe(III)-IIP was used to study preconcentration and recovery of Fe(III) from water samples.
