摘要：
The use of ceramic membrane in liquid pollution treatment is actually limited due to the price of ceramic membrane, nevertheless these membranes are more resistant to solvent, pH and oxidation. In this work the preparation of low cost TiO2(50%)-ZnAl2O4(50%) membranes deposited on an artificial cordierite support is presented. The pores diameter of the membrane is centered on 4nm, the water flux is 6.4 l(-1) m(2) h(-1) bar(-1), thickness and molecular weight cut-off are respectively 1.2 mu m and 3,000Da. High rejection of classical ionic solutes, heavy metal and dyes were obtained by a classical mechanism of Donnan exclusion. This kind of membrane gave promising results for possible wastewater treatment in emergent countries.
