Abstract

Procédé pour épurer une solution aqueuse. Selon le procédé de l'invention, on met la solution aqueuse en contact avec un échangeur de cations acide et ensuite avec un polymère ou polycondensat contenant du soufre sous forme de groupements thiols liés à des atomes de carbone. Le procédé est particulièrement approprié à l'emploi pour des solutions d'hydrates de carbone et des solutions de matières qui peuvent être obtenues lors de l'extraction et/ou de la fabrication d'hydrates de carbones à partir de produits intermédiaires, finals ou résiduels. Application à l'industrie chimique.
