Study on the Adsorption Equilibrium of Acetone in Aqueous Solution on Activated Carbon

The adsorption equilibrium for acetone on activated carbon was measured, the data obtained was well correlated in Freundlich isotherm form. Isosteric heat of adsorption which was determined from ClausisClapeyron equation decreased with the amount adsorbed increasing. It was caused by the activated carbon surface energetical heterogeneity and the interaction between the acetone.
