摘要： The Polanyi-Dubinin equation was used to predict adsorption isotherms for eight organic vapors at 25℃and for two organic vapors at 25℃, 40℃and 60℃on activated carbon in this analysis. The theoretical affinity coefficient, β, was calculated by three methods (molar volume, molecular parachor and electronic polarization) based on nonpolar and polar reference vapors.
