Adsorption of Tritium -containing Dihydrogens on the Crystalline Zeolite A
External Surface
Abstract
GS adsorption
radiochromatography was successfuly applied to measure, for the first time,
the HT, DT and T2
adsorption heats on the crystalline zeolite
A ( potassium form KA ) external surface . At the temperatures 77
- 70 K the measured adsorption heats are ( kJ/mole ): 8.5( HT ), 9.9( DT ),
10.7( T2 ) being about 15% lower than corresponding values for
NaA volume (internal) adsorption.
For KA the Henri region adsorption is reached at the sample tritium quantity
lower than 170 femtomole.
