主权项

1. A method for producing iron(III) citrate comprising:
a step of forming an iron-containing precipitate comprising bringing ferric chloride into contact with sodium hydroxide in an aqueous medium for a duration of two hours or less at a liquid temperature of 0° C. to 10° C. to form an iron-containing precipitate; a step of generating an aqueous solution of iron(III) citrate comprising bringing citric acid into contact with the iron-containing precipitate in an aqueous medium and generating an aqueous solution of iron(III) citrate via heating; and a step of precipitating iron(III) citrate comprising bringing the aqueous solution of iron(III) citrate into contact with an organic solvent to precipitate the iron(III) citrate.
