Comparative Analysis of Various Adsorbents for Low-Temperature Separation of a 20Ne–22Ne Isotopic Mixture

A method to obtain analytical expressions for evaluation of adsorption isotherms of neon isotopes at cryogenic temperatures is proposed. Adsorption isotherms of 20Ne and 22Ne on BAU activated carbon at 77 K are evaluated. The results allow the degree of influence of the pressure and composition of the 20Ne–22Ne isotopic mixture on the separation factor to be estimated.
