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.
