Abstract

A new method for treating U-containing wastewater and recovering of uranium simultaneously by electro-deposition was proposed. The complexity of adsorbent preparation and difficulty in uranium recovery that existed in traditional adsorption method are solved by electro-deposition approach. The iron and graphite are used as anode electrode and cathode electrode in this experiment, respectively. The innovative view in this study is to promote the rapid generation of magnetite stemmed from iron dissolution under direct current. The uranium is incorporated or adsorbed to the magnetite through accurate controlling experimental conditions. The effects of initial U-concentration, voltage, electrode spacing, ion concentration, pH value on uranium removal efficiencies were investigated. Uranium removal efficiencies reached 83.5% under laboratory conditions that uranium concentration at 10mg/L, voltage at 30V, electrode spacing at 5 cm, ion concentration at 3 g/L, at pH 3.45. It is the advantages of U-containing magnetic is easily separated from aqueous solution and can be utilized as secondary low grade uranium deposit after treatment that making this method has a bright prospect.
