摘要：
The problem of conversion of an isotherm of excess adsorption measured experimentally into values of the total amount of the adsorbate (absolute adsorption) has been formulated. Five isotherms of excess adsorption of krypton on NaA zeolite were measured (at 334--500 K) at equilibrium pressures of similar to 160 MPa. The corresponding isotherms of the total amount were calculated and the temperature dependences of the parameters of an equation describing the isotherms of excess adsorption were identified, it was shown that al high temperatures and pressures, krypton atoms diffuse into the beta-cavities of the NaA zeolite.
