Abstract:
1. A method for removing arsenic from a fluid medium comprising the steps of: providing an akaganeite by dissolving a ferric chloride in water to form a ferric chloride solution; incubating the ferric chloride solution so that the ferric chloride is hydrolyzed; harvesting the akaganeite; concentrating the akaganeite in an aqueous solution; providing a carrier medium; attaching the akaganeite to the carrier medium to form an akaganeite laden medium; contacting the fluid medium containing arsenic with the akaganeite laden medium so that the arsenic is absorbed onto the akaganeite; and separating the akaganeite laden medium from the fluid medium so that the arsenic is removed from the fluid medium.
