Process for the preparation of trivalent iron complexes with mono-, di- andpolysaccharide sugars, consisting of the activation of the sugar by oxidationwith nascent bromine generated in situ by reaction be tween an alkaline oralkaline earth bromine and an alkaline hypochlorite, the complexation of theactivated sugar in solution with a ferric salt dissolved in an aqueoussolution, the purification of the resulting solution through ultrafiltrationand finally the stabilization of the trivalent iron-sugar complex by heatingat a temperature between 60~C and 100~C for a period between 1 and 4 hours ata pH between 9.0 and 11Ø
