| Abstract: | The support was made by adopting granulometric sintering process, and the α-Al_2O_3 membrane was prepared by sol-gel method. The finally made unsymmetrical inorganic ceramic ultrafilter membrane had a deusity of 2.703 g/cm~3 and a porosity of 23.51%. The pore size of the membrane was measured using probe molecules (Cr black T, methyl orange and so on). The results indicate that the ultrafilter membrane has a holding back relative molecular mass of 327~417, that is, the pore size is about 2 nm and the water permeability is 2000~3450 mL/m~2·h. |
