Removal of Toxic Uranium from Synthetic Nuclear Power Reactor Effluents Using Uranyl Ion Imprinted Polymer Particles

摘要: Major quantities of uranium find use as nuclear fuel in power reactors. In view the extreme toxicity and consequent stringent limits fixed by WHO various national governments, it is essential to remove from reactor effluents before discharge into environment. Ion imprinted polymer (IIP) materials have traditionally been used for recovery dilute aqueous solutions prior detection or seawater. We now describe IIP selective removal a typical synthetic effluent. The were prepared uranyl ion (imprint ion) forming binary salicylaldoxime (SALO) 4-vinylpyridine (VP) ternary SALO-VP complexes 2-methoxyethanol (porogen) copolymerizing presence styrene (monomer), divinylbenzene (cross-linking monomer), 2,2'-azobisisobutyronitrile (initiator). resulting then ground sieved obtain unleached particles. Leached particles obtained leaching imprint ions with 6.0 M HCl. Control also analogously without ion. complex alone gave quantitative pH range 3.5-5.0 low 0.08 g. retention capacity was found be 98.50 mg/g polymer. present study successfully demonstrates feasibility removing selectively 5 microg - 300 mg 500 mL effluent containing host other inorganic species.
