Thin film composite ultrafiltration membrane which possesses desirable properties or characteristics may be prepared by casting a solution of a polyelectrolyte complex on a microporous support to form a thin film of the polyelectrolyte complex on the surface of the supports. The thickness of the polyelectrolyte complex membrane will range from about 600 to about 3,000 ANGSTROM . This membrane may then be used for the separation of low molecular weight solutes such as, for example, the separation of glucose from sucrose and higher molecular weight sugars. |
