Immobilization of uranium into magnetite (Fe3O4), which was generated from metallic iron by electrochemical method, was proposed to rapidly remove uranium from aqueous solution. The effects of electrochemical parameters such as electrode materials, voltage, electrode gap, reaction time and pH value on the crystallization of Fe3O4 and uranium removal efficiencies were investigated. More than 90% uranium in the solution was precipitated with Fe3O4 under laboratory conditions when uranium concentration range from 0.5 mg/L to 10 mg/L. The Fe3O4 cry...
