Description of benzene adsorption in slit-like pores. Theoretical foundations of the improved Horvath–Kawazoe method Original Research Article

The improved Horvath–Kawzoe method (IHKM) proposed by Ustinov and Do was studied by theoretical, numerical, and experimental approaches. The IHKM analysis was improved by incorporation of new numerical algorithms (REG and ASA). The benzene adsorption isotherms on carbon blacks and activated carbons at 293 K were measured for proving the new theoretical treatment. This theory gives a more better description of these observed adsorption isotherms. We can conclude that, presented theory can be applied to analyze others adsorption isotherms, proving reasonable pore structures for activated carbons.
