Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 22 (Novembre 2009) . - pp. 9823–9829 Titre : Preparation of biomimetic materials made from polyaspartyl polymer and chitosan for heavy-metal removal Type de document : texte imprimé Auteurs : Bo Sun, Auteur ; Zhen-Tao Mi, Auteur ; Gang An, Auteur Année de publication : 2010 Article en page(s) : pp. 9823–9829 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Polyaspartyl  polymer  Chitosan  Peptide−polysaccharide-resembling  structure Résumé : By the combination of polyaspartyl polymer and chitosan, a kind of novel environmentally friendly biomimetic blend material with peptide−polysaccharide-resembling structure was synthesized for heavy-metal removal. The resulting blend possesses diversified functional groups and was further modified by introducing a mercapto group through esterification between thioglycollic acid and hydroxyl group in the structure of chitosan. The polyaspartyl polymer−chitosan blend with 2.2 wt % mercapto group content improves the adsorption of organic compounds of mercury and arsenic. The blend exhibits a lower swelling behavior in the presence of water and is verified to have a potential biodegradability by elemental analysis and infrared spectrum (FT-IR).
