The Preparation and Characterization of Geopolymer Based Inorganic Membranes

Abstract:

In this work, the geopolymer based inorganic membranes, as a kind of new inorganic membranes, were synthesized with water-glass, metakaolin and deionized water. The resulting membranes were characterized by SEM, water flux and pore size. The results show that the membranes have high strength and water flux when these membranes were fabricated under the preparation condition: water-glass modulus of 1.1, Na/Al molar ratio of 0.8 and H₂O/Na₂O molar ratio of 18.
