Temperature dependence of adsorption coefficients of 222Rn on activated charcoal determined by adsorption-desorption method.
Adsorption coefficients of 222Rn on five activated charcoal were determined (at -21, +7 and +26 degrees C) by an adsorption-desorption technique using a radon source and an Erlenmeyer flask. They varied from 1.1 to 41.2 L x g(-1). From this variation the mean heat of adsorption of radon on our charcoal was calculated as equal to 4,630(50) cal/mole.
