Description of an Active Carbon Micropore Size Distribution Based on the Horvath—Kawazoe Equation Adapted to Benzene Adsorption Isotherms
The Horvath–Kawazoe equation has been used for the determination of the pore size distribution (PSD) of four fractions of active carbon separated by elutriation on the basis of their different degrees of activation. A comparison of the pore size distribution functions for argon and benzene as adsorb...
