Chemistry, Physics and Technology of Surface| Summary: | An equation of the adsorption isotherm for cylindrical pores with the diameter of 1-4 Van-der-Waals diameters of the adsorbate molecule has been suggested. It was obtained within the theory of volume filling of micropores where the pores are filling with molecular associate-cluster without surface tension similar to the process of capillary condensation. The equation of volumetric filling is formally analogous to Kelvin equation with the potential energy of the cluster as the key parameter. The resulting equation was tested for the adsorption of nitrogen on Davisil and methanol on silica gel. |
