A Theoretical and Experimental Study of Physical Adsorption of Gases on Uniform Flat Solid Surface

摘要

In this work we have experimentally observed the phsisorption isotherms for nitrogen, TMS, cyclohexane, benzene, and n-hexane adsorbed on flat aluminum foil surface and have analyzed them theoretically on the basis of the theory proposed by Chang et al. The results show that the theory by Chang et al. can provide a useful means to describe the physisorption of gases on uniform flat solid surface which is essentially important for analysis of the pore volume distribution in porous solid surface. We have also discussed the application of the results obtained in this work to the analysis of pore volume distribution in porous alumina we reported previously.
