چکیده:

Water/UDMH mixtures were separated at ambient temperature and atmospheric pressure by pervaporation (PV) using home-made NaA zeolite membranes. These membranes showed very high selectivity of water for all UDMH mixtures. Separation factor as high as 52000 was obtained for UDMH feed concentration of 5%. Total mass flux was also obtained in a range of 0.30-0.62 kg/ (m2.h). The results confirm the superior performance of the zeolite membranes for dehydration of water/UDMH mixtures.
