Abstract
Purification d'une solution aqueuse de chlorure de sodium. Dans une cuve d'électrolyse à membrane 1 d'échange de cations à chambre 2 anodique et à chambre 3 cathodique, munie également d'une cuve 4 pour l'anolyte, d'une cuve 5 pour le catholyte, d'un conduit 6 pour le chlore gazeux, d'un conduit 7 pour l'hydrogène gazeux et d'un conduit 8 pour la solution purifiée de chlorure de sodium, on fait circuler une suspension d'impuretés avec addition d'un réactif chimique de séparation par précipitation des impuretés. Industries électrochimiques.
