Abstract

LAS MEZCLAS DE BROMUROS DE ALQUILO O BROMUROS DE ALQUILENO PREFLUORADAS, QUE CONTIENEN COMPUESTOS DE YODO PERFLUORADOS, SON IRRADIADOS CON UNA RADIACION ELECTROMAGNETICA, EN LA BANDA DE LONGITUD DE ONDA DE 230 A 500 NM, Y BIEN DURANTE LA RADIACION O BIEN INMEDIATAMENTE DESPUES SE PONEN EN CONTACTO CON AL MENOS UNO DE LOS AGENTES SIGUIENTES: CARBONO ACTIVO, DETERMINADOS METALES EN PARTICULAS PEQUEÑAS, ALCOHOLES BAJOS ALIFATICOS, CLORO, BROMO, OXIGENO, PEROXIDO DE HIDROGENO, SOLUCIONES ACUOSAS O ALCOHOLICAS DE COMPUESTOS DE METALES ALCALINOS CON ANIONES DETERMINADOS INORGANICOS O CON ALCOHOLES BAJOS ALIFATICOS. DESPUES DE LA SEPARACION DEL MEDIO Y, DADO EL CASO, LA DESTILACION PUEDEN OBTENERSE COMPUESTOS DE YODO QUE CONTIENEN POR DEBAJO DE 0,0005% EN PESO Y QUE SON UTILIZABLES P. EJ. EN EL SECTOR MEDICO.
