Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 N° 23 (Décembre 2008) . - p. 9596–9600 Titre : Modeling of the phase equilibrium for aqueous solutions of brij 58 surfactant and three salts Type de document : texte imprimé Auteurs : Masumeh Foroutan, Auteur ; Maryam Mohammadlou, Auteur Année de publication : 2009 Article en page(s) : p. 9596–9600 Note générale : Chemistry engineering Langues : Anglais (eng) Mots-clés : Equilibrium Three salts Résumé : The osmotic virial model and the Flory−Huggins model, with the Debye−Huckel equation as an electrostatic term, have been used to correlate the liquid−liquid equilibrium data for an aqueous solution of polyoxyethylene cetyl ether surfactant (abbreviated as Brij 58) and three inorganic salts (containing NH4H2PO4, (NH4)2HPO4, and Brij58−KH2PO4) at 298.15 K. The results have shown that the maximum absolute deviation from experimental data is less than 0.6% and 1.4% for the osmotic virial model and the Flory−Huggins theory, respectively. These models are in good agreement with experimental data.
