Synthesis and characterization of imprinted polymers for radioactive waste reduction / Anupkumar Bhaskarapillai in Industrial & engineering chemistry research, Vol. 48 N° 8 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 8 (Avril 2009) . - pp. 3730–3737 Titre : Synthesis and characterization of imprinted polymers for radioactive waste reduction Type de document : texte imprimé Auteurs : Anupkumar Bhaskarapillai, Auteur ; Narasimhan V. Sevilimedu, Auteur ; Börje Sellergren, Auteur Année de publication : 2009 Article en page(s) : pp. 3730–3737 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Imprinted  polymer  Radioactive  waste  generated  Nuclear  reactors Résumé : A cobalt(II) imprinted polymer, that could lead to significant reduction in radioactive waste volume generated during decontamination of nuclear reactors, was synthesized using [N-(4-vinylbenzyl) imino]diacetic acid as the functional monomer through two different methods. The imprinted polymer was found to selectively trap cobalt(II) ions even when present in ppb levels from strong complexing medium against excess ferrous ions. It showed no uptake of ferrous ions under the conditions tested. Cobalt sorption and desorption were found to be rapid. The cobalt selectivity of the polymer was also demonstrated with radioactive cobaltous ions wherein it showed 55% reduction in cobalt activity from a complexing solution containing 2 μCi of radioactive cobalt along with excess ferrous ions. The selectivity of the polymer was compared to that of a commercial resin containing similar functional ligand.
