Abstract
METODO DE PURIFICACION DE PEROXIDO DE HIDROGENO DE ANIONES. LA INVENCION SE REFIERE A UN METODO PARA LA PURIFICACION DE PEROXIDO DE HIDROGENO DE ANIONES. SEGUN EL METODO, SE PONE EN CONTACTO UNA SOLUCION ACUOSA DE PEROXIDO DE HIDROGENO DE AL MENOS 20% P/P CON UNA RESINA ANIONICA MEDIA DE FORMA BASICA QUE TIENE UNA MATRIZ DE ESTIRENO DIVINILBENCENO, A UNA TEMPERATURA ENTRE 0GC Y EL PUNTO DE CONGELACION DE LA SOLUCION, PREFERIBLEMENTE A UNA TEMPERATURA INFERIOR A -8GC, DURANTE SU TRATAMIENTO CON LA RESINA.
