Title (EN) POLYIMIDE MEMBRANE
(FR) MEMBRANE DE POLYIMIDE
Abstract: front page image
(EN)A high mass transfer membrane for use in membrane phase contactors to extract a solute from an aqueous phase to a solvent phase and their method of preparation and use are disclosed. The membrane is formed from polyimide by phase inversion and may optionally be crosslinked to maintain stability even in the solvents from which the membranes were formed by phase phase inversion.
(FR)La présente invention concerne une membrane de transfert de masse élevée destinée à être utilisée dans des contacteurs de phase à membrane pour extraire un soluté en phase aqueuse et le faire passer en phase de solvant. L'invention porte aussi sur les procédés de préparation et d'utilisation correspondants. La membrane est obtenue à partir d'un polyimide au moyen d'une inversion de phase et peut éventuellement être réticulée pour maintenir sa stabilité et ce, même dans les solvants à partir desquels les membranes ont été obtenues suite à une inversion de phase.
