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

Аннотация

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.
