Abstract: The present disclosure is directed to metal ion-containing zeolitic compositions, preferably transition metal ion-containing, more preferably zinc ion containing zeolitic compositions, that are useful for reversibly scavenging water from humid gaseous feed streams, including air, and method of making and using the same. In some embodiments, the compositions comprise zinc-ion-doped zeolites have LTA, FAU, or EMT topologies.
