Abstract
The adsorption of CFC-11, 12, 13 and 113 on NaY, KY and CsY zeolites w as carried out by use of a conventional static adsorption apparatus an d the data were discussed in terms of the best fit isotherms. An infle ction point was observed on each experimental isotherm at the adsorpti on amount of ca. 1.5 molecules per unit cavity. The heat of adsorption calculated by Clausius-Clapeyron equation between 0 and 25-degrees-C on NaY zeolite increased with increasing adsorption amount of CFC-11, 12 and 113. These data were explained in terms of the equations propos ed by Hill and Kieselev.
