Abstract
METODO DE SEPARACION DE IMPUREZAS DE ACIDO HUMINICO DE UNA SOLUCION ACIDICA QUE CONTIENE METAL. SE PONE EN CONTACTO LA SOLUCION ACIDICA QUE CONTIENE ACIDO HUMINICO, PARTICULARMENTE FOSFORICO, CON UN AGENTE DEPURADOR EN UN MEZCLADOR-SEDIMENTADOR; EL AGENTE DEPURADOR CONSTA DE: UN MATERIAL EXTRACTOR DEL METAL ORGANICO CON BAJA SOLUBILIDAD EN LA SOLUCION ACIDICA, FORMANDO EN DICHA SOLUCION UN DERIVADO CON IONES DE METAL, PUDIENDO SER UNA MEZCLA DE ACIDO DIALQUILFOSFORICO CON OXIDO DE TRIALQUILFOSFINA EN RELACION DE 3 A 5 POR 1, Y DE UN DISOLVENTE, DE HIDROCARBURO ORGANICO PARA EL MATERIAL EXTRACTOR DE METAL, PARTICULARMENTE KEROSENO CON TEMPERATURA DE EBULLICION COMPRENDIDA EN EL MARGEN 150-300GC, UNA SOLUBILIDAD LIMITADA EN LA SOLUCION ACIDICA Y CONSTITUYENDO UN 50 A UN 90 POR 100 DEL AGENTE DEPURADOR EN VOLUMEN. EL AGENTE DEPURADOR INTERACCIONA CON LAS IMPUREZAS DE ACIDO HUMINICO, QUE PREVIAMENTE SE HA OXIDADO CON ACIDO NITRICO, FORMANDO DOS FASES: UNA PRIMERA DE LODO DE IMPUREZAS Y OTRA FORMADA POR LA SOLUCION ACIDICA PURIFICADA QUE PASA POSTERIORMENTE POR UN DISPOSITIVO DE EXTRACCION DE METALES. SE APLICA COMO UNA PREDEPURACION DEL ACIDO FOSFORICO EN EL PROCEDIMIENTO DE RECUPERACION DE URANIO. C
