Synthesis and Analytical Applications of Uranyl Ion Imprinted Polymer Particles

Abstract

Uranyl ion imprinted polymer particles were prepared by the copolymerization of styrene monomer and a crosslinking agent divinyl benzene in the presence of -5,7-dichloroquinoline-8-ol-4-vinyl pyridine ternary complex as template where in is the imprint ion in presence of 2,2′-azo-bis-isobutyronitrile as initiator. The Uranyl ion was removed from the polymer particles by leaching with 1:1 HCl, which leaves cavities in the polymer particles. The leached polymer particles preconcentrate ion from dilute aqueous and synthetic seawater solutions. Further, these particles find use in the separation of ion from various bivalent, trivalent, and tetravalent, inorganic ions. The accuracy of the developed enrichment procedure was tested by analyzing marine sediment certified reference material supplied by National Research Council (NRC), Canada. Further, the developed procedure has been successfully employed to analyze real soil and sediment samples.
