Abstract

. LA INVENCION SE REFIERE A UNA CELULA ELECTROQUIMICA, EN PARTICULAR PARA ELECTRODIALISIS CON FINES DE RECONCENTRACION DE ACIDO CROMICO, DEL TIPO QUE COMPRENDE AL MENOS UN COMPARTIMENTO ANODICO QUE ALBERGA CADA UNO, RESPECTIVAMENTE, UN CATODO Y UN ANODO Y SEPARADOS POR AL MENOS UNA MEMBRANA INTERCAMBIADORA DE IONES. SEGUN LA INVENCION, LA CELULA SE REALIZA CON FORMA DE UN APILAMIENTO APRETADO DE COMPARTIMENTOS CATODICOS Y ANODICOS, CARACTERIZADA EN QUE CADA COMPARTIMENTO ESTA DEFINIDO POR UN MARCO RIGIDO (110) DEL QUE AL MENOS UN BRAZO (114) ESTA ATRAVESADO POR UNA ABERTURA (115) Y EN QUE CADA ELECTRODO (180, 190), FIJADO SOBRE UN SOPORTE (160, 170), ES APTO PARA SER MONTADO DE MANERA AMOVIBLE EN SU MARCO RESPECTIVO DESDE EL EXTERIOR, A TRAVES DE DICHA ABERTURA, POR FIJACION ESTANCA DE CADA SOPORTE DE ELECTRODO SOBRE EL MARCO ASOCIADO.
