Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 9 (Mai 2011) . - pp. 5727-5732 Titre : Removal of boron using nylon-based chelating fibers Type de document : texte imprimé Auteurs : Kohsuke Ikeda, Auteur ; Daisuke Umeno, Auteur ; Kyoichi Saito, Auteur Année de publication : 2011 Article en page(s) : pp. 5727-5732 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Nylon  Fibers Résumé : By using electron-beam-induced graft polymerization, an epoxy-group-containing monomer, glycidyl methacrylate (GMA), was appended onto a 6-nylon fiber; subsequently, N-methylglucamine as a chelate-forming moiety was added to the epoxy group. The chelating group density of the resultant chelating fiber was 2.0 mmol/g, which was 74% of that of a commercially available chelating bead containing the same functionality. A 150 mg-B/L boron solution was forced to flow through the chelating-fiber-packed bed at the space velocity range from 10 to 100 h−1, defined by dividing flow rate by bed volume (0.3 mL). At a space velocity of 20 h−1, the dynamic binding capacity of the chelating-fiber-packed bed was 2.5-fold higher than that of the chelating-bead-packed bed.
