Abstract

PROCEDIMIENTO DE ELECTRODIALISIS CON MEMBRANA BIPOLAR (BP) PARA LA REGENERACION DE ACIDOS SEGUN EL CUAL SE REALIZA ENTRE UN ELECTRODO POSITIVO (ANODO) Y UN ELECTRODO NEGATIVO (CATODO) UNA SUCESION DE COMPARTIMIENTOS BASE B, ACIDO A, SAL S, DETERMINADOS POR UNA SUCESION DE MEMBRANAS CATIONICA, BIPOLAR, ANIONICA, CATIODICA, BIPOLAR, ETC..., CIRCULANDO UNA SOLUCION EN CADA COMPARTIMIENTO. SE APLICA CONTRA LA CARA ANIONICA (11) DE LA MEMBRANA BIPOLAR (BP), UNA MEMBRANA ANIONICA SUPLEMENTARIA (10), SIN DEJAR NINGUNA SEPARACION MEDIBLE ENTRE LAS DOS MEMBRANAS, PARA REDUCIR LA CONTAMINACION EL COMPARTIMIENTO ACIDO POR CATIONES.
