Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 18 (Septembre 2011) . - pp. 10516-10524 Titre : MIL-53(Al) : an efficient adsorbent for the removal of nitrobenzene from aqueous solutions Type de document : texte imprimé Auteurs : Dinesh V. Patil, Auteur ; Phani B. Somayajulu Rallapalli, Auteur ; Ganga P. Dangi, Auteur Année de publication : 2011 Article en page(s) : pp. 10516-10524 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Aqueous  solution Résumé : MIL-53(Al), hydrothermally synthesized and purified by solvent extraction, was used as adsorbent for the removal of nitrobenzene from aqueous solution. Pristine MIL-53(Al) and MIL-53(Al) loaded with various amounts of nitrobenzene were characterized by X-ray diffraction analysis with cell indexation study, thermogravimetric analysis, Fourier transform infrared spectroscopy, and BET surface area. A simulation study of nitrobenzene adsorption on MIL-53(Al) was performed. The adsorption study of nitrobenzene on MIL-53(Al) was carried out at 30 ± 1 °C using batch experiments. The amount of nitrobenzene adsorbed decreases with an increase in the temperature from 30° to 60 °C and pH from 8 to 11, whereas no significant difference was observed in acidic pH. The adsorption data were fitted to Sips and Redlich―Peterson isotherm models. The adsorption capacity of nitrobenzene on MIL-53(Al) obtained was 610 mg/g, higher than that of zeolites (267.2 mg/g) and organoclays (100 mg/g), but, lower than that of modified commercial activated carbons (1443.53 mg/g).
