A stable dependence of the gas retentivity of carbon absorbents on the structure and polarity of their surface is found. This relation makes it possible to predict the sorption properties and determines their parameters from chromatographic data. The sorptivity of high-polarizability molecules is most affected not by the total volume of the micropores but rather by the width of the micropore-size distribution and the surface polarity of the sorbents.
