METHODS FOR PRODUCING CARBOXYLATE LIGAND MODIFIED FERRIC IRON HYDROXIDE COLLOIDS AND RELATED COMPOSITIONS AND USES

摘要

Processes for recovering colloids of carboxylate ligand modified ferric iron hydroxide materials such as IHAT (Iron Hydroxide Adipate Tartrate) are described based on the use of water miscible non-aqueous solvents, such as ethanol, methanol and acetone. The processes produce materials with advantageous properties such as improved bioavailability, reduced aggregation and/or agglomeration and/or increased iron content.
