| 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 HNO3
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 |
