Zusammenfassung:The present invention relates to an improved process for the preparation of pharmaceutical grade of Sucroferric oxyhydroxide (1). More particularly, the present invention relates to a process for the preparation of Sucroferric oxyhydroxide (1) specific surface area of more than 16 m2/gm and having phosphate binding capacity by Ion Chromatography (IC) is at least 2.6 meq. of phosphate per 500 mg Iron and at least 0.2 mg P/mg of Iron. La présente invention concerne un procédé amélioré pour la préparation de qualité pharmaceutique de l'oxyhydroxyde sucroferrique (1). Plus particulièrement, la présente invention concerne un procédé pour la préparation d'une surface spécifique d'oxyhydroxyde sucroferrique (1) de plus de 16 m2/gm et ayant une capacité de liaison au phosphate par chromatographie ionique (IC) est d'au moins 2,6 meq. de phosphate pour 500 mg de fer et au moins 0,2 Mg de P/mg de fer.
