摘要：
In this paper we present a detailed experimental study of molecular adsorption on interfaces of silica gels from binary solutions of alcohol/toluene. The adsorption measurements are corroborated with infrared spectra of the surface hydroxyl groups and with NMR results. The adsorption isotherms are analyzed within the framework of the Everett approach and possible scaling relations between alcohol monolayer capacities and adsorbate cross sections are discussed. We conclude that reliable morphological information on the interfaces cannot be obtained from these adsorption experiments.
