Natural zeolites as effective adsorbents in water and wastewater treatment / Shaobin Wang in Chemical engineering journal, Vol. 156 N° 1 (Janvier 2010) 

Public ISBD [article]  in Chemical engineering journal > Vol. 156 N° 1 (Janvier 2010) . - pp. 11-24 Titre : Natural zeolites as effective adsorbents in water and wastewater treatment Type de document : texte imprimé Auteurs : Shaobin Wang, Auteur ; Yuelian Peng, Auteur Année de publication : 2010 Article en page(s) : pp. 11-24 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Natural  zeolite  Adsorption  Inorganic  ions  Organics  Water  treatment Index. décimale : 660 Résumé : Natural zeolites are abundant and low cost resources, which are crystalline hydrated aluminosilicates with a framework structure containing pores occupied by water, alkali and alkaline earth cations. Due to their high cation-exchange ability as well as to the molecular sieve properties, natural zeolites have been widely used as adsorbents in separation and purification processes in the past decades. In this paper, we review the recent development of natural zeolites as adsorbents in water and wastewater treatment. The properties and modification of natural zeolite are discussed. Various natural zeolites around the world have shown varying ion-exchange capacity for cations such as ammonium and heavy metal ions. Some zeolites also show adsorption of anions and organics from aqueous solution. Modification of natural zeolites can be done in several methods such as acid treatment, ion exchange, and surfactant functionalisation, making the modified zeolites achieving higher adsorption capacity for organics and anions.
