Influence of exchanged cations (Na+, Cs+, Sr2+ and Ba2+) on xylene permeation through ZSM-5/SS tubular membranes
(Elsevier Science, 2008-07)
Na-ZSM-5 membranes were synthesized by secondary growth on the outer surface of stainless steel porous tubes. The membranes were ion-exchanged with Cs+, Ba2+ and Sr2+ to investigate their effect upon the separation of ...
