Abstract:

Nano stable boehmite sol was initially synthesized by hydrolysis of metal salt method. Then γ-alumina intermediate layerwas prepared by dip coating of supports in boehmite sol and calcination process. Titania top layer was also synthesizedproperly on the obtained samples by hydrolysis of alkoxide technique .These layers were uniform with low defects andthickness of about 6.02 mand 1m, respectively. Decrease of pores from micro to nano scale led to considerablepermeation decrease. Final membrane can be used for nanofilteratio process.
