Abstract

The object of the work presented in this thesis was to obtain quantitative values of the thermodynamic changes in water upon adsorption by kaolinite. Two methode were used. The first was a determination of the differential heat content and entropy of adsorption. The second method included a thermodynamic evaluation of the B.E.T. "c" constant expressed in terms of the Gibbs standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential and standard thermodynamic functions or free energy, entropy, and heat content of adsorption. The adsorption of water on kaolinite appears to be a van der Waals type of adsorption, the heats of adsorption being from 4.4-2.5 k. cal mole-1 more negative than the heat of condensation or water.
