ABSTRACT:
A novel selective permeable membrane is made by cross-linking of chitosan by aldehyde, preferably by dialdehyde. The dialdehyde cross-linked membrane has a remarkably high separation efficiency for water-alcohol solution due to hydrophilic property of chitosan and its very dense structure obtained by the cross-linking of chitosan with dialdehyde.
