Abstract
Abstract The interaction between 1,1,2-trichloro-1,2,2-trifluoroethane (Freon TF) and uranium dioxide was investigated from a series of gravimetric adsorption measurements in the temperature range −15 to 28°C. All of the isotherms were Type II and completely reversible obeying the BET adsorption equation. Adsorption data also could be fit to the Freundlich equation which suggested a heterogeneous surface. The isosteric heat of adsorption varied from 8.6 to 5.8 kcal/mole as coverage increased and reached a minimum at a coverage of 1.5 molecular layers. The cross-sectional area of the adsorbed molecule was calculated from BET data to be 40A 2 . Adsorption of Freon TF was compared to the adsorption of other chlorinated solvents using the potential theory of adsorption.
