FIELD: production of adsorbent.
SUBSTANCE: proposed method consists in mixing zeolite A either with aqueous solution of silver salt or with solid salt for exchange of Na ions by Ag ions at definite parameters of process. Proposed method makes it possible to produce adsorbent at high capacity for nitrogen and argon and selectivity relative to nitrogen and argon as compared with oxygen.
EFFECT: enhanced efficiency.
