▎ 摘　　要

NOVELTY - Co-producing and recovering uranium in water involves using photo-catalysis-electro-oxidation by, adding photocatalyst to the uranium-containing waste liquid, under the illumination condition, photo generated electron to reduce and deposit uranium ion in the uranium containing waste liquid on the surface of the photocatalyst, performing electrochemical oxidation of the uranium, desorption in electrochemical oxidant electrolyte, and introducing ammonia gas into the electrochemical oxide electrolyte with uranium until the precipitate is completely precipitated solid-liquid separation, recycling the precipitation precipitate, and realizing the recovery of uranium. USE - Method for co-producing and recycling uranium in water for repeated and effective utilization of uranium. ADVANTAGE - The method can realize effective enrichment and separation of uranium in uranium-containing waste liquid, it has important meaning for repeated and effective utilization of uranium, it promotes the absorption and enrichment of the reduced uranium on the surface, improving the enrichment efficiency, based on the characteristic of the strong conductive ability of graphene oxide, it can overcome the technical problem of bad electrochemical efficiency caused by the low conductivity of the titanium dioxide, so as to accelerate the oxidation desorption process of the uranium in subsequent electrochemical oxidation process, it promotes the uranium absorbed photocatalyst the surface to be quickly transferred to the electrolyte solution. DESCRIPTION OF DRAWING(S) - The drawing shows three circulating light catalytic-electrooxidation co-production uranium recycling efficiency.
