【 摘 要 】

In the present work, NaX zeolite membranes were synthesized via secondary growth using vacuum seeding method. NaX zeolite suspension solution for vacuum seeding was prepared at various concentration and the resultant seeded supports with homogeneous coverage were selected for hydrothermal synthesis. The resultant membranes were characterized using XRD, SEM and EDX analysis. The XRD results showed that NaX zeolite membranes were successfully formed and the SEM images revealed that continuous zeolite membrane layer was obtained.
