ACS Appl Mater Interfaces. 2015 Jul 1;7(25):13728-30. doi: 10.1021/acsami.5b04085. Epub 2015 Jun 16.

Abstract

Highly stable FAU-type zeolite membrane for the separation of isopropanol (IPA)-water mixture by pervaporation is described. FAU membrane showed high water permselectivity and permeance. Comparison of FAU membrane with a conventional LTA-type zeolite membrane revealed superior stability of FAU zeolite membrane in a mixture containing a large water content.

Keywords: pervaporation; separation and purification; vapor permeation; zeolite membrane.
