摘要：

Commercial ultrafiltration ceramic filters have been modified by chemical treatment. The gamma-Al2O3 top layer of the asymmetric ceramic filter was modified (I) by in situ hydrolysis of tetraethylorthosilicate, giving a hydrophilic nanoporous SiOx top layer rich in Si-OH, (2) by silylation of the gamma-Al2O3 layer, providing an organophilic functionalization, and (3) by reaction of the gamma-Al2O3 layer with alkyl/aryl phosphonic acids, resulting in an organophobic behaviour. By these chemical treatments both a pore narrowing and a hydrophilic/hydrophobic functionalization can be achieved. Permeation results of single gases and pervaporation data of liquid mixtures on the novel membranes are presented. (C) 1998 Elsevier Science B.V. All rights reserved.
