CALCULATION OF HENRY CONSTANTS OF ADSORPTION OF NOBLE-GASES ON IDEALIZED SURFACE OF TALC

The proportionality constants between the gas pressure and occupancy o f the idealized talc surface were computed for noble gases Helium, Neo n, Argon, Krypton and Xenon covering the temperature range 100 K - 450 K. Interaction potential noble gas atom - solid phase was calculated using summations of interaction potentials of Lennard-Jones type. The values of Henry's constants of adsorption were calculated using known formula based on computation of configuration integral. The one-partic le configuration integral was calculated using the classical mechanics limit. The assumption of ideality of both, free gas and adsorbed phas e, was used. The obtained values of Henry's constant are in qualitativ e agreement with the values estimated from experimental adsorption iso therms for analogical systems.
