IN-SITU COMPLEX MEMBRANE - DEHYDRATION OF PYRIDINE AQUEOUS-SOLUTION BY PERVAPORATION

In this study, we proposed in-situ complex(ISC) membrane as a new type of PIC. We adapted simple acid/base reaction to invent the ISC membra ne and applied to the dehydration of pyridine aqueous solution. ISC fo rms from the interaction of pyridine in feed and acid moiety in membra ne and enhances the water transport through the membrane because of it s hydrophilic nature. We compared the separation results by using ISC concept with those of non-ISC membranes and investigated the effect of the concentration of acid moiety in the membrane on the dehydration o f pyridine/water mixture.
