Abstract

METODO PARA LA PREPARACION Y PURIFICACION DE UN COMPLEJO DE OXIDO-HIDROXIDO FERRICO Y UN HIDRATO DE CARBONO.CONSISTE EN QUE UNA SOLUCION DE CLORURO FERRICO CON UN CONTENIDO EN FE EQUIVALENTE, SE LE AÑADE UNA SOLUCION DE CARBONATO ALCALINO ALCANZANDO LA MEZCLA UN PH ENTRE 1,2 Y 1,6. A CONTINUACION SE LE AÑADE UNA SOLUCION DE HIDRATO DE CARBONO COMO DEXTRANO PARA OBTENER UN COMPLEJO ESTABLE CON EL OXIDO-HIDROXIDO FERRICO. SE NEUTRALIZA LA MEZCLA CON UNA SOLUCION ALCALINA HASTA UN PH DE 2 A 2,2, AÑADIENDOSE EN EXCESO 50 A 150 SOBRE LA CANTIDAD NECESARIA LA SOLUCIONDE HIDRATO DE CARBONO, Y SE NEUTRALIZA CON SOLUCION ALCALINA HASTA UN PH DE 4 A 4,5. LA MEZCLA ASI OBTENIDA SE PASA POR DOS COLUMNAS QUE CONTIENEN MICROESFERAS DE UN DIAMETRO ENTRE 0,1 Y 1,5 MM O BIEN MICROPARTICULAS DE FORMA IRREGULAR DE TAMAÑO EQUIVALENTE, FORMADAS POR GELES DE POLIMEROS DE DEXTRANO. EL GEL DE LA PRIMERA COLUMNA TIENE UN TAMAÑO DE PORO QUE PERMITE SOLAMENTE LA ENTRADA DE LOS IONES DE LA SAL Y EXCLUYE AL HIDRATO DECARBONO LIBRE Y AL COMPLEJO DE HIDRATO DE CARBONO Y OXIDO-HIDROXIDO FERRICO. LA SEGUNDA COLUMNA SE HA RELLENADO CONARIA LA SOLUCIONUN GEL QUE PERMITE LA ENTRADA DEL HIDRATO DE CARBONO LIBRE Y EXCLUYE AL COMPLEJO DE HIDRATO DE CARBONO Y OXIDO-HIDROXIDO FERRICO.
