A Pseudo second - order kinetic expression for dissolution kinetic profiles of solids in solutions / K. Vasanth Kumar in Industrial & engineering chemistry research, Vol. 49 N° 16 (Août 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 16 (Août 2010) . - pp 7257–7262 Titre : A Pseudo second - order kinetic expression for dissolution kinetic profiles of solids in solutions Type de document : texte imprimé Auteurs : K. Vasanth Kumar, Auteur ; Issam A. Khaddour, Auteur ; Vinod K. Gupta, Auteur Année de publication : 2010 Article en page(s) : pp 7257–7262 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Kinetic  Solids Résumé : A pseudo second-order kinetic expression was presented to explain the dissolution kinetics of solids in solution. The kinetic constant, initial dissolution rate, and theoretical saturation concentration according to pseudo second-order kinetic expression was defined. The proposed expression successfully represents the published dissolution kinetic profiles of alumina, digoxin, benzoic acid, lead chloride, and lecithin in solutions. A pseudo second-order kinetics based on fractional conversion successfully represents the dissolution kinetics of ulexite in ammonium acetate solutions. The pseudo second-order kinetics enabled the prediction of dissolution kinetics for higher residence time from experimental data obtained in relatively short time.

Rice husk and its ash as low - cost adsorbents in water and wastewater treatment / M. Ahmaruzzaman in Industrial & engineering chemistry research, Vol. 50 N° 24 (Décembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 24 (Décembre 2011) . - pp. 13589–13613 Titre : Rice husk and its ash as low - cost adsorbents in water and wastewater treatment Type de document : texte imprimé Auteurs : M. Ahmaruzzaman, Auteur ; Vinod K. Gupta, Auteur Année de publication : 2012 Article en page(s) : pp. 13589–13613 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Adsorbents  Water  Wastewater  treatment Résumé : Rice husk, which is a relatively abundant and inexpensive material, is currently being investigated as an adsorbent for the removal of various pollutants from water and wastewaters. Various pollutants, such as dyes, phenols, organic compounds, pesticides, inorganic anions, and heavy metals can be removed very effectively with rice husk as an adsorbent. This article presents a brief review on the role of rice husk and rice husk ash in the removal of various pollutants from wastewater. Studies on the adsorption of various pollutants by rice husk materials are reviewed and the adsorption mechanism, influencing factors, favorable conditions, etc., discussed in this article. It is evident from the review that rice husk and its ash can be potentially utilized for the removal of various pollutants from water and wastewaters.
