Abstract
The binary separation factors for H-2-HT and D2-DT adsorption at the N aA zeolite were determined in batch equilibration experiments between 22 and 140 K. The equations for the separation factor temperature depe ndence were obtained. The experimentally obtained separation factor va lues for alpha(H-2)-HT = 69 at 22 K, and for alpha(D2)-DT = 4.3 at 25 K, are significantly higher then those obtained in liquid hydrogen fra ctionation. Absorption by NaA zeolite is proposed for concentration of tritium and its removal from hydrogen.
