Abstract

DE ACUERDO CON LA INVENCION, UTILIZANDO EL PRINCIPIO ELECTROCINETICO PARA UN METODO PARA LA LIMPIEZA DE MATERIALES CONTAMINADOS CON METALES PESADOS, Y MEDIANTE EL CUAL SE HACE USO DE UN APARATO QUE COMPRENDE DOS MEMBRANAS DE INTERCAMBIO DE IONES SELECTIVAS EN CARGA CON CARGAS DIFERENTES COMBINADAS CON UNA CAMARA DE SOLUCION DE ELECTROLITO INTERIOR Y UNA CAMARA DE SOLUCION DE ELECTROLITO EXTERIOR QUE ESTAN SEPARADAS DE LAS MEMBRANAS QUE SIRVEN COMO UNA FUNCION DE BLOQUEO, SE CONSIGUE UN GRADO SORPRENDENTEMENTE BUENO DE UTILIZACION ESPECIALMENTE EN RELACION CON EL CONSUMO DE CORRIENTE, Y AL MISMO TIEMPO LA PRECIPITACION DE LOS METALES PESADOS ES TAN EFECTIVA QUE PUEDEN SER REUTILIZADOS. POR LO TANTO, SE CONSIGUE UN GRADO HASTA AHORA DESCONOCIDO DE APROVECHAMIENTO EN COMPARACION CON LOS METODOS CONOCIDOS DE LIMPIEZA.
