Application of a Temperature-Dependmiempirical thermodynamic ion-exchange model to a multicomponent natural zeolite system / Kathryn A. Mumford in Industrial & engineering chemistry research, Vol. 47 n°21 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°21 (Novembre 2008) . - p. 8347–8354 Titre : Application of a Temperature-Dependmiempirical thermodynamic ion-exchange model to a multicomponent natural zeolite system Type de document : texte imprimé Auteurs : Kathryn A. Mumford, Auteur ; David C. Shallcross, Auteur ; Ian Snape, Auteur ; Geoff W. Stevens, Auteur Année de publication : 2008 Article en page(s) : p. 8347–8354 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Semiempirical  thermodynamic Résumé : A recently developed temperature-dependent semiempirical thermodynamic ion-exchange model is used to predict ion-exchange equilibrium behavior of a binary and ternary system onto a natural zeolite material. The ion-exchange system involves the cations ammonium, potassium, and calcium, at chloride concentrations ranging from 0.005 to 0.25 M and temperatures ranging from 4.0 to 40.0 °C ± 0.2 °C. The model describes the ion-exchange behavior well, considering the natural variability of the zeolite material.
