BET Modeling of Solid–Liquid Phase Diagrams of Common Ion Binary Salt Hydrate Mixtures. I. The BET Parameters

摘要

Solid–liquid phase diagrams of binary salt hydrate mixtures can be modeled by means of the BET method, next paper, which considers the water as if it were “adsorbed” on “sites” of the salt. The parameter r describes the average number of sites and ε describes the molar enthalpy of adsorption in excess of the enthalpy of condensation of water vapor. The BET parameters r and ε required for the modeling were obtained for a large number of salts from water activities or related quantities of concentrated aqueous solutions of them. This paper consists of a comprehensive compilation of these two BET parameters for a large number of salts.
