Abstract

Pervaporation membranes were fabricated by blending different amount of zeolite NaA or NaX with three types of poly(amidesulfonamide) (PASA). The zeolitefilled membranes were characterized by IR spectroscopy, SEM, sorption measurements, and wide-angle X-ray diffraction. By adding the proper amount of NaA into the polymer casting solutions, the resultant zeolite-filled membranes exhibited improvement in both selectivity and permeability in the separation of 10% aqueous solutions of ethanol and propan-1-ol, as compared with the zeolite free membrane.
