Intermolecular Repulsions in Adsorbed Layers.

Adsorbate-adsorbate interactions are analyzed in the framework of the Ono-Kondo model. The results show that, at large amounts of adsorption, intermolecular interactions in the adsorbed phase are repulsive. In the range of small adsorption, microporous systems also can show repulsions due to limitations of the adsorption space. This effect also is possible in macroporous adsorbents with active site spacing that is less than that of the adsorbate bulk liquid. Copyright 2000 Academic Press.
