Abstract: The selective removal of aluminium ions has been extensively investigated by applying several techniques. Among them, the use of specific polymeric adsorbents has been considered one of the most promising techniques[1]. Ion imprinted polymers(IIPs)are recently identified nano-porous polymeric materials which on leaching the imprint ion can rebind, sense or transport (when cast as membranes) selectively the target analyte in presence of closely related inorganic ions. The IIPs find interesting applications in solid phase extraction, sensors and membrane separations of inorganics[2]. In this study ,we have prepared a novel ion imprinted polymer(IIP) to removal aluminium ions in solution samples.The imprinted polymer was prepared by copolymerization of allyl glycidyl ether/iminodiacetic acid (AGE/IDA) as functional monomers in the presence of N,N'-Methylenebisacrylamide as crosslinker. The polymerization was carried out in bulk with free radical initiation using 2,2'-azobisisobutyronitrile(AIBN). The polymer particles were characterized by Fourier transform inferared (FT-IR),scanning electron microscopy(SEM)and elemental analysis. The effect of various experimental conditions ,eg.pH,adsorption and desorption time and volume of eluent on the extraction efficiency were investigated and optimized. The optimum pH for quantitative aluminium retention was 5,while elution was completed with 5 mL of 0.5 M nitric acid. The influence of various cationic interferences on percent recovery of complex was studied. The results clear revealed that the Al(III) content was retained completely by the IIP ,even in the presence of the diverse ions. The total capacity of IIP was found to be 62.4 mg g-1 in 20 C. The method was applied to the recovery and determination of aluminium in different real samples. The imprinted polymers exhibited good characteristics for adsorption and preconcentration of target aluminium. Finally, the IIP beads can be used many times without decreasing their adsorption capacities significantly
