Authors : R. Mansoor Kazemimoghadam,Zahra Amiri Rigi,

https://doi.org/10.29294/IJASE.4.2.2017.537-546

Zeolite membranes have uniform and molecular-sized pores that separate molecules based on the differences in the molecules’ adsorption and diffusion properties. Strong electrostatic interaction between ionic sites and water molecules (due to its highly polar nature) makes the zeolite NaA membrane very hydrophilic. Zeolite NaA membranes are thus well suited for the separation of... Read More
