Role of Number of Imprinted cavity on The Selectivity of the Imprinted Polymer

Abstract

Research on the effect of the number of imprinted cavities on the mechanisms of the selectivity of the imprinted polymer method was conducted. These imprinted materials studied were based on eugenol as a functional monomer while PEGDE (Polyethylene Glycol Diglycidyl Ether) and EDMA (Ethylene Glycol Dimethacrylate) used as cross linker. The first step of synthesis of material was by interacting the ion template Fe (III) on polyeugenol and polyeugenoxi acetate. The next step was locking the complex with cross linker PEGDE (polyeugenol) or EGDMA (polyeugenol and polyeugenoxi acetate). The macropolymer formed were then eliminated its Fe(III) using an acid to formed Ionic Imprinted Polymer (IIP). The IIP formed was then analyzed by SEM EDX to determine concentration of Fe (III) in the polymer. The results obtained show that the concentration of the Fe (III trapped in macropolymer was 1.5% in the interacted step with template. After being released by acid, 0.15; 0.6; 1.03; 1.06% of Fe (III) were still remaining in the polymer. The smaller the number of Fe (III) remaining in polymer, it can be expected that many imprinted cavity was formed. The more imprinted cavity formed, it can be obtained the higher degree of selectivity of adsorption.
