Incorporation of silver ions into zirconium titanium phosphate / Niranjan Biswal in Industrial & engineering chemistry research, Vol. 50 N° 16 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 16 (Août 2011) . - pp. 9479-9486 Titre : Incorporation of silver ions into zirconium titanium phosphate : a novel approach toward antibacterial activity Type de document : texte imprimé Auteurs : Niranjan Biswal, Auteur ; Satyabadi Martha, Auteur ; Umakanta Subudhi, Auteur Année de publication : 2011 Article en page(s) : pp. 9479-9486 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Ions  Zirconium  Titanium  Phosphate Résumé : Silver exchanged zirconium titanium phosphates (Ag–ZTPs) are interesting materials because of their best antibacterial performance toward Escherichia coli (E. coli). Silver ions were incorporated into zirconium titanium phosphate (ZTP), a composite ion-exchanger, by an ion-exchange process conducted at 65 °C. This study focuses on the most thorough investigation of their synthesis, optical spectroscopy, absorption band (vibrational and rotational levels) spectra, morphology studies, elemental analysis, and antibacterial activity. Silver-exchanged zirconium titanium phosphates (Ag–ZTPs) were characterized by XRD (BAXS), DRUV–vis, FTIR, XPS, SEM-EDS, TEM, and AAS measurement. Silver ions are incorporated into ZTP which is well-known from X-ray photoelectron study, transmission electron microscopy, and energy dispersive spectra. It was found that 250 mg L–1 of 5 wt % Ag–ZTP possesses high antibacterial activity with 99% inhibition within 12 h of contact. Therefore, the present results strongly suggest the effective use of silver-exchanged zirconium titanium phosphates as antibacterial agents.
