Abstract

LA PRESENTE INVENCIÓN PROVEE UN MÉTODO QUE PERMITE DETERMINAR EFICIENTEMENTE EL FINAL DE LA SEPARACIÓN DEL YODO ADSORBIDO POR UN CARBÓN ACTIVADO, DONDE UNA SOLUCIÓN DE SEPARACIÓN ES PASADA A TRAVÉS DE UN CARBÓN ACTIVADO EN EL CUAL EL YODO ESTA ADSORBIDO, EL POTENCIAL DE OXIDACIÓN-REDUCCIÓN DE UNA SOLUCIÓN POST-SEPARACIÓN HA ALCANZADO MENOS QUE O IGUAL A 180 MV (ELECTRODO DE REFERENCIA DE AG-AGCI), ENTONCES ES DETERMINADA LA FINALIZACIÓN DE LA SEPARACIÓN CUANDO EL PH LLEGUE A SER MÁS QUE O IGUAL A 1,5, Y LA RELACIÓN DE UN REDUCTOR, QUE NO HA REACCIONADO, ALCANZA MÁS QUE O IGUAL A 60%.               THE PRESENT INVENTION PROVIDES A METHOD THAT ALLOWS TO EFFICIENTLY DETERMINE THE END OF THE SEPARATION OF THE IODINE ADSORBED BY AN ACTIVATED CARBON, WHERE A SEPARATION SOLUTION IS PASSED THROUGH AN ACTIVATED CARBON IN WHICH THE IODINE IS ADSORBED, OR THE POTENCY IS ADSORBED A POST-SEPARATION SOLUTION HAS REACHED LESS THAN OR EQUAL TO 180 MV (AG-AGCI REFERENCE ELECTRODE), THEN THE COMPLETION OF THE SEPARATION IS DETERMINED WHEN THE PH BECOMES MORE THAN OR EQUAL TO 1.5, AND THE RATIO OF A REDUCER, WHICH HAS NOT REACTED, REACHES MORE THAN OR EQUAL TO 60%.
