Dodge and Francis [9] have developed a process to recover toxic metals including uranium from soils using citric acid and visible light photodegradation. Early studies showed that the uranyl ion is photochemically active in the presence of organic acids, and on exposure to visible light, a uranyl citrate complex undergoes photochemical oxidation/reduction reactions. The studies of Dodge and Francis showed that, although the uranyl citrate complex is not biodegradable, the photochemical degradation results in the precipitation of uranium as an insoluble oxide. The citric acid and contaminated soil or sludge is first treated with bacteria which degrades, free of complexed citric acid, to carbon dioxide and water. The supernatant containing the uranium-citrate complex is then separated and subjected to photodegradation for uranium recovery
