Abstract
PROCEDE POUR L'ELIMINATION D'IMPURETES PRESENTES A RAISON DE QUELQUES PARTIES PAR MILLIARD DANS DES SAUMURES DE CHLORURES DE METAUX ALCALINS. CE PROCEDE DE PURIFICATION D'UNE SAUMURE DE CHLORURE DE METAL ALCALIN DONT LA TENEUR EN CHLORURE DE METAL ALCALIN EST DE 225 A 325 G PAR LITRE ET CONTENANT 200 A 500 PARTIES PAR MILLIARD D'ION DE METAUX ALCALINO-TERREUX, EST CARACTERISE EN CE QU'IL CONSISTE : A MAINTENIR ALCALIN LE PH DE LA SAUMURE, A AJOUTER UN PHOSPHATE A LADITE SAUMURE ALCALINE DE FACON A FORMER UN PRECIPITE INSOLUBLE, ET A SEPARER CE PRECIPITE INSOLUBLE D'AVEC LA SAUMURE. APPLICATION DE CE PROCEDE A L'ELECTROLYSE DES SAUMURES DE CHLORURES DE METAUX ALCALINS POUR L'OBTENTION DE CHLORE ET DE SOUDE.
