Title: Treatment of arsenic-contaminated water using akaganeite adsorption

Abstract

The present invention comprises a method and composition using akaganeite, an iron oxide, as an ion adsorption medium for the removal of arsenic from water and affixing it onto carrier media so that it can be used in filtration systems.
