Abstract: The porous alumina menbranes supported on porous ceramic of pore size 1.1~1. 6um were prepared by the sol-gel method,following repeated impregnating-drying-calcin-ing procedures. The number of repeating cycles could be reduced when the sols were modi-fied by PVA and La (NO3)3.

Key words: supported membrane, porous alumina membrane, preparation, sol-gel method
