Extraction of uranium from water: A strategy based on tribocatalysis
Due to most of the U(VI) extraction methods suffering the issues of high cost and low efficiency, finding a new method is still urgent. In this work, we report a way to remove U(VI) from water by tribocatalysis, where a natural mineral of attapulgite is used as the tribocatalyst. By a careful investigation, it is confirmed that the ultrasonic-generated microbubbles rub with the attapulgite to form free radicals of h+, ·O2-, and ·OH, which could then be transformed to H2O2 to react with U(VI) to form UO2O2. The extraction rate of U(VI) from water is up to 87.88% (50 ppm) in 200 min. This work using the natural mineral attapulgite being tribocatalyst has the advantages of low cost and high efficiency, which also provide new insight into the conversion of U(VI) in natural conditions and will have great potential in the treatment of nuclide wastewater and seawater.
期刊介绍：
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
