Title (EN) THIN FILM COMPOSITE ULTRAFILTRATION MEMBRANE
(FR) MEMBRANE D'ULTRAFILTRATION COMPOSITE A FILM MINCE
Abstract:
(EN) 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 Å. 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.
(FR) On peut préparer une membrane d'ultrafiltration composite à film mince possédant des propriétés et des caractéristiques recherchées, en coulant une solution formée d'un complexe polyélectrolyte sur un support microporeux pour former un film mince de complexe polyélectrolyte sur la surface du support. L'épaisseur de la membrane du complexe polyélectrolyte est comprise entre environ 600 et 3000 Å. On peut ensuite utiliser cette membrane pour séparer des solutés à faible poids moléculaire, par exemple pour séparer le glucose du saccharose et de sucres ayant un poids moléculaire plus élevé.
