Analysis of argon isotope separation by low temperature adsorption
Bauman Moscow State Technical University, Moscow, 105005, Russia
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.
Key words: low-temperature adsorption / adsorption isotherm / adsorption of the isotopes / inert gases / argon
