Isotherms, isosteres, and enthalpy of adsorption of 1,2-dichloroethane from aqueous solution onto activated carbons / Robert Pełech in Industrial & engineering chemistry research, Vol. 47 n°15 (Août 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°15 (Août 2008) . - p. 5615-5622 Titre : Isotherms, isosteres, and enthalpy of adsorption of 1,2-dichloroethane from aqueous solution onto activated carbons Type de document : texte imprimé Auteurs : Robert Pełech, Auteur Année de publication : 2008 Article en page(s) : p. 5615-5622 Note générale : Bibliogr. p. 5622 Langues : Anglais (eng) Mots-clés : 1,2-dichloroethane  --  adsorption;  Dubinin-Astakhov  equation;  Freundlich  equation; Résumé : In this work the adsorption of 1,2-dichloroethane from aqueous solutions onto DTO, AG5, and WD-ekstra activated carbons has been studied. The adsorption isotherms at the range of temperatures 298-343 K have been described by the Freundlich and Dubinin-Astakhov equations. The characteristic curves of the adsorption process have been determined. It was found out that the temperature dependence of the adsorption equilibrium was described well by the Dubinin-Astakhov model. The isosteric enthalpy of the adsorption was assigned. To describe the dependence of the adsorption isosteric enthalpy on the filling degree, the Do model and the combinations of the van’t Hoff and Dubinin-Astakhov equations in a form of the logarithmic equation were used.
