The adsorbability on active carbons of substances with different physicochemical properties has been investigated and a comparative analysis of the pore structure parameters of the active carbons as estimated from the sorption of substances with various molecular diameters has been made. The influence of the surface chemistry of carbon sorbents on the adsorption of water vapour has also been studied. The need for a quantitative analysis of the pore structure parameters and the surface chemistry of active carbons as a basis for their universal characterization is discussed.
