Abstract

METODO PARA LA PURIFICACION DE AGUA QUE CONTENGA MEZCLAS CONTAMINANTES, QUE UTILIZA UN REACTOR QUE CONTIENE UN SEMICONDUCTOR COMO CATALIZADOR DE REACCION Y UNA LAMPARA QUE EMITE RADIACIONES CON UNA LONGITUD DE ONDA INFERIOR A 400 NM. EL REACTOR, CARACTERIZADO POR QUE SUS PAREDES PERMITEN EL PASO DEL AGUA Y SUSTANCIAS CONTAMINANTES, SE INTRODUCE EN EL AGUA QUE SE VAYA A PURIFICAR PARA QUE LOS CONTAMINANTES CONTENIDOS EN LA MISMA ALCANCEN EL INTERIOR DEL REACTOR EN DONDE SON ABSORBIDOS EN EL SEMICONDUCTOR ACTIVADO POR LA RADIACION DE LUZ, DEGRADANDOSE CON POSTERIORIDAD.
