AbstractAbstract
[en] Constituents of an acid in slightly ionized aqueous solution are separated by electrodialysis, dissociation is obtained inside a membrane containing grafted functional groups on an inert support. For membrane fabrication chloromethylated groups, then aminated functional groups are grafted on a polymer. Application is made to adjust boric acid content in the water of the primary cooling circuit of a nuclear reactor

Pour separer, par electrodialyse, les constituants d'un acide en solution aqueuse faiblement ionisee, on effectue la dissociation des constituants par reaction, au sein d'une membrane a support neutre, avec des groupements fonctionnels greffes sur la membrane. Pour fabriquer la membrane, on greffe sur le support un polymere comportant avantageusement des sites chloromethyles puis des sites fonctionnels amines. Le procede est utilisable pour ajuster la teneur en acide borique de l'eau constituant refrigerant d'un reacteur nucleaireOriginal Title
Procede de separation de constituants d'un acide faible, notamment d'acide borique et membrane pour la mise en oeuvre dudit procede
