Abstract: front page image
(EN)The present invention provides an ion exchange membrane having a porous polymeric support grafted with an organic moiety to which is covalently bonded at least one ion exchange group, and methods for preparing the ion exchange membrane. A method for treating a fluid containing ions wherein ions are removed by contacting the fluid with an ion exchange membrane of the present invention is also provided. In addition, the present invention provides a filtration apparatus for removing ions from a fluid, which filtration apparatus utilizes an ion exchange membrane of the present invention.
(FR)L'invention porte sur une membrane échangeuse d'ions comportant un support polymère poreux greffé par un fragment organique auquel est lié par covalence au moins un groupe échangeur d'ions ainsi que sur des procédés de préparation de la membrane échangeuse d'ions.
