Title:
STRONTIUM-EXCHANGED CLINOPTILOLITE
Document Type and Number:
WIPO Patent Application WO/2013/094193
Kind Code:
A1
Abstract:
[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.
