Abstract

EL INVENTO SE REFIERE A UN MATERIAL DE FILTRO ABSORBENTE LIBRE DE CROMIO Y METODO PARA ELIMINAR GASES TOXICOS.EL MATERIAL DE FILTRO ES UN CARBON ACTIVADO DEL TIPO WELTERITA IMPREGNADO DE COBRE, PLATA, Y MOLIBDENO Y/O SALES DE VANADIO JUNTO CON TRIETILENEDIAMINA Y RETIENE ESENCIALMENTE LA EFECTIVIDAD DEL CROMIO SIMILAR QUE CONTIENE WELTERITAS PARA PROTEGER SIN EL PELIGRO CARCINOGENICO QUE PRESENTA EL CROMO. EL NUEVO MATERIAL TAMBIEN LIBERA MENOS OLOR AMONIACAL QUE EL CROMO CONVENCIONAL.
