A formalism for describing the adsorption of gaseous mixtures at solid surfaces was derived as an extension of the BET theory. The following additional assumptions were made; the composition of all the adsorbed layers is the same and interaction occurs between the component molecules in the adsorbed layers. The proposed equations were compared with the experimental data obtained from measurements of the adsorption of an acetone—methanol mixture onto N-type active carbon.
