Titre : Impregnating zirconium phosphate onto porous polymers for lead removal from waters : effect of nanosized particles and polymer chemistry Type de document : texte imprimé Auteurs : Qingrui Zhang, Auteur ; Peijuan Jiang, Auteur ; Bingcai Pan, Auteur Année de publication : 2009 Article en page(s) : pp. 4495–4499 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Polymer-based zirconium phosphate Chloromethylated polystyrene Polystyrene cation exchange resin X-ray diffraction Résumé : The subject study revealed several unique properties of polymer-based zirconium phosphate (ZrP) for lead removal from waters. ZrP particles were impregnated within two porous polymers, namely, a chloromethylated polystyrene (CP) and a polystyrene cation exchange resin (D-001). Both as-prepared hybrid sorbents (designated ZrP−CP and ZrP−001, respectively) were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and a N2 adsorption−desorption test at 77 K. As compared to the fresh particles, ZrP impregnated onto CP exhibits a slight increase in sorption capacity, which may result from their nanosized particles after impregnation. More attractively, ZrP−001 displays much higher sorption preference toward lead ions over calcium ions than ZrP, D-001, and ZrP−CP. Such significant phenomena is mainly attributed to the Donnan membrane effect exerted by the immobilized sulfonate groups on D-001 and further validates its potential application for enhanced removal of the toxic metal from contaminated waters.
