Abstract

OBTENCION DE DICROMATOS DE METALES ALCALINOS, ACIDO CROMICO O UNA MEZCLA DE DICROMATOS DE METAL ALCALINO Y ACIDO CROMICO POR ELECTROLISIS DE SOLUCIONES QUE LOS CONTIENEN EN CELULAS ELECTROLITICAS DE DOS CAMARAS, CUYAS CAVIDADES ANODICAS Y CATODICAS ESTAN SEPARADAS POR UNA MEMBRANA INTERCAMBIADORA DE CATIONES DE UNA SOLA CAPA BASADO EN POLIMEROS PERFLUORADOS CON GRUPOS DE ACIDO SULFONICOQUE COMPRENDE: INTRODUCIR LAS SOLUCIONES EN LA CAMARA ANODICA Y ELECTROLIZAR DICHA SOLUCION PARA FORMAR UN ANOLITO QUE CONTIENE DICROMATO DE METAL ALCALINO, ACIDO CROMICO O UNA MEZCLA DE SOLUCIONES DE MONOCROMATO DE METAL ALCALINO Y ACIDO CROMICO EN LA CAMARA ANODICA Y 2) INTRODUCIR LAS SOLUCIONES EN LA CAMARA CATODICA PARA GENERAR UN CATOLITO ACUOSO QUE CONTIENE CROMATO CON UN PH DE 4 A 14 EN LA CAMARA CATODICA.
