Conclusion

  1. 1.

    The application of two adsorption models — the adsorbed-solution model and the dispersed-phase model — to the analysis of the dependence of the thermodynamic functions of an adsorption system on the parameters of the adsorption equilibrium permits the adsorption system to be regarded as a solution at small degrees of filling and as a dispersed phase at high degrees of filling.

  2. 2.

    The presence of maxima on the curves of the temperature dependence of the isosteric heat capacity of the adsorbate at high degrees of filling apparently indicates the presence of associates of molecules in the adsorbate, as a consequence which the properties of the adsorption system gradually approach the properties of the equilibrium gas phase.
