Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELIMINACION DEL HIERRO DEL ACIDO FOSFORICO PREPARADO MEDIANTE UN PROCESO HUMEDO. LOS IONES DE FE3+ PRESENTES COMO IMPUREZAS EN EL ACIDO FOSFORICO SON REDUCIDOS A IONES DE FE2+. DESPUES DE LA REDUCCION, LOS IONES DE FE2+ PUEDEN ELIMINARSE DEL ACIDO FOSFORICO MEDIANTE INTERCAMBIO CATIONICO DE IONES.
