摘要：
The adsorption of CFC-11, 12, 13 and 113 on NaY, KY and CsY zeolites was carried out by use of a conventional static adsorption apparatus and the data were discussed in terms of the best fit isotherms. An inflection point was observed on each experimental isotherm at the adsorption 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 proposed by Hill and Kieselev.
