STRONTIUM-EXCHANGED CLINOPTILOLITE

摘要

[Problem] To provide: strontium ion-exchanged clinoptilolite having excellent nitrogen-adsorbing properties; and a method for producing the strontium ion-exchanged clinoptilolite. [Solution] Synthetic clinoptilolite having a strontium ion at an ion exchange site thereof is useful as a nitrogen adsorbent. The synthetic clinoptilolite can be produced by bringing a solution containing a strontium ion into contact with synthetic clinoptilolite under ambient pressure to cause ion exchange.
