“…The separation of a mixture of isotopes of inert gases is of particular interest today. Inert gas isotopes are used to obtain various radioisotopes, in MRI machines, in particle accelerators, in fast neutron detectors, for physical and medical research [1,2,3]. Experimental separation of a mixture of isotopes is a complex and laborious process; therefore, it is especially important to obtain calculated values of the separations coefficients At present, rectification, thermal diffusion and centrifugation are used to separate isotopes of inert gases, which have a number of disadvantages, including large mass and size characteristics, the presence of moving elements, the impossibility of separation of more than two components, and a complex automation system.…”

In this work, the estimated calculated values of the critical parameters of argon isotopes 36Ar, 38Ar, 40Ar and the corresponding values of the constants of the Van der Waals, Redlich-Kwong and Peng-Robinson equations of state are obtained. The data obtained make it possible to calculate the adsorption isotherms of argon isotopes on microporous adsorbents. The technique proposed for obtaining analytical expressions for the adsorption isotherms of argon isotopes at cryogenic temperatures makes it possible to estimate the degree of influence of the pressure of the isotope mixture and its composition on the mixture separations coefficients.
