A New Theoretical Isotherm Equation for Water Vapor-Food Systems: Multilayer Adsorption on Heterogeneous Surfaces
Journal of Food Engineering
A new analytical isotherm equation that can be applicable to water vapor-food systems was developed. The model describes the multilayer adsorption on energetically heterogeneous surfaces by assuming that the local isotherm for a specific site is given by the GAB isotherm, and the distribution of energetically different sites is represented by a generalized exponential function. The new isotherm was tested, using published experimental data. Results showed that the model provides an accurate and simple description of the adsorption characteristics for heterogeneous adsorbents. © 1993.
