THE ADSORPTION OF KRYPTON ON GRAPHITE ABOVE AND BELOW THE TRIPLE POINT

Abstract
The adsorption of krypton on graphite has been measured above and below its Triple Point. Above the Triple Point, a smooth isotherm was found which showed two types of hysteresis. In contrast, the isotherm measured below the Triple Point displayed two discontinuities. The surface area of this graphite measured by means of the krypton isotherm was found to be in agreement with that previously measured by nitrogen adsorption.
