Description
Summary:The mechanism of polar substances sorption on active carbons have been discussed using some aliphatic alcohols as an example. An effort has been undertaken to determine the role of both the specic adsorbate-adsorbent sorption and the adsorbate-adsorbate association in the total sorption of studied alcohols. It has been stated that, at small filling degrees, there is no consistence with the theory of volume filling of micropores because of the existence of both the association and the specific adsorbate-adsorbent interactions. An analysis of changes in fundamental thermodynamic functions has shown that, at great filling degrees, the fundamental assumptions of Dubinin's theory can be realized.
