摘要：

A statistical thermodynamical model is proposed for describing the temperature-dependent equilibrium distribution of different types of cations among the crystallographically different sublattices in zeolites. Thermodynamic functions relating to ion exchange involving several groups of homogeneous sites can be derived. On the basis of the Gibbs-Duhem relation, it is shown that no standard chemical potentials, and hence no specific ion-exchange equilibrium constants, of a cation in a site of a zeolite can be defined.
