Abstract

PROCESO DE FABRICACION DE UNA MEMBRANA BIPOLAR, SEGUN EL CUAL SE TRATA UNA MEMBRANA CATIONICA CON UN COMPUESTO DE UN METAL POLIVALENTE Y CON UNA SOLUCION ACUOSA DE HIDROXIDO DE METAL ALCALINO QUE COMPRENDE HIDROXIDO DE LITIO, Y DESPUES SE PEGA A UNA MEMBRANA ANIONICA. LA MEMBRANA BIPOLAR ENCUENTRA UNA APLICACION EN LA FABRICACION DE SOLUCIONES ACUOSAS DE HIDROXIDO DE SODIO POR ELECTRODIALISIS.
