MOLDING ELUTING DIVALENT IRON IONS BY USING ORGANIC SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide a molding eluting divalent iron ions, which can elute efficiently divalent iron ions inexpensively using organic substances.

SOLUTION: The divalent iron ion-eluting molding which produces divalent iron ions in water by submerging is provided. The organic substances and scrap or powdery iron are mixed, are loaded into a reduced-form heat treat furnace, and are subjected to a heating reduction treatment at a low oxygen atmosphere state, by which a sintered body of the obtained reduced iron and charcoal, and a mixture of the reduced iron and charcoal are molded in a powdery or granular state.
