英文摘要	The ionic imprinted polymer (IIP) of uranyl ion (UO2 (2+)) as the template was synthesized by the formation of binary complexes of UO2 (2+) with 2,4-dioxopentan-3-yl methacrylate as functional monomer followed by thermal copolymerization with ethylene glycol dimethacrylate as cross-linking monomer in the presence of 2,2'-azobisisobutyronitrile as initiator and 1,4-dioxane as porogenic solvent. 50 mmol L-1 HCl solution was used to leach out UO2 (2+) ions from the IIP. Similarly, the control polymer was prepared under identical experimental conditions without using UO2 (2+) ions. The above synthesized polymers were characterized by infra-red spectroscopy, thermo-gravimetric analysis and Barrett-Emmett-Teller surface area measurement. The maximum adsorption capacities of IIP and CP in (NH4)(4)[UO2(CO3)(3)] solution were 15.3 and 11.2 mg U g(-1), respectively. The kinetics of adsorption followed a pseudo-second-order rate equation. The prepared IIP was successfully used to extract uranium from real seawater sample.; Chemistry, Analytical; Chemistry, Inorganic & Nuclear; Nuclear Science & Technology; SCI(E); 0; ARTICLE; 3; 1705-1712; 298
