Abstract
PROCEDIMIENTO DE EXTRACCION DE METALES DE TRANSICION DE UNA SOLUCION DE DESCONTAMINACION Y LIMPIEZA. COMPRENDE: A) CARGAR UNA RESINA CAMBIADORA DE ANION, COMO UNA RESINA DE POLIESTIRENO FUERTEMENTE BASIFICADA, CON UN AGENTE COMPLEJANTE, COMO EL ACIDO ETILENDIAMINOTETRAACETICO O UNA SAL METALICA ALCALINA DEL MISMO, CUYA CONSTANTE DE EQUILIBRIO PARA LA FORMACION DEL COMPLEJO CON ION FERRICO ES DE 1022; Y B) HACER CIRCULAR LA SOLUCION QUE CONTIENE EL ION FERRICO, COMO METAL DE TRANSICION, Y ACIDO CITRICO Y OXALICO, ENTRE 40 Y 100JC, HASTA QUE EL PH DE LA SOLUCION SEA INFERIOR A 6. TIENE APLICACION EN LAS SOLUCIONES DE DESCONTAMINACION QUE SE USAN EN LA LIMPIEZA DE LOS SISTEMAS DE REFRIGERACION DE LAS CENTRALES NUCLEARES.
