Abstract: Ion recognition-based separation techniques have received much attention because of their high selectivity for target ions.[1-6] In this study, we have prepared a novel ion imprinted polymer (IIP) to remove nickel ions in solution samples. The imprinted polymer was prepared by copolymerization of Allyl glaycidyl ether / Imminodiaceticacid (AGE/ IDA) with N,N Dimethylacrylamid as functional monomers in the presence of N,N bismethylenacrylamid as cross linker. At first, AGE/IDA was prepared and then the ion imprinted polymer was synthesiezed. The polymerization was carried out in bulk with free radical initiation using 2,2 Azobis isobutyronitryl. The above synthesized polymers were characterized by Fourier transform inferared Spectroscopy (FT-IR), Elemental analysis, Scanning electron microscope analysis (SEM) and Thermogravimetric analysis (TGA). The total capacity of IIP was found to be 58.3 mg/g in 20°C, respectively. The optimum pH value for sorption of the metal ion was 4.5. Less than 5 min and 150 rpm shaking was required for 90% sorption. A recovery of 93.6% was obtained for the metal ion with 0.1 M, H2SO4 as the eluting agent .The effect of K+ , Mg2+, Ca2+ , Zn2+, Cu2+ and Cd2+ ions was investigated to evaluate the selectivity. This polymer was applied successfully for Nickel ion determination in environmental samples
