NOVELTY - A composite adsorbent for treating uranium-containing radioactive wastewater comprises graphene oxide and manganese oxide. USE - Composite adsorbent for removal of nuclide e.g. radionuclide uranium in uranium-containing radioactive wastewater (claimed). ADVANTAGE - The composite adsorbent is prepared by simple process with excellent adsorption performance to the nuclide uranium in the low radioactive wastewater. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of composite adsorbent for treating uranium-containing radioactive wastewater, which involves mixing graphene oxide with deionized water to obtain oxidized graphene suspension, adding potassium permanganate and concentrated hydrochloric acid to suspension, ultrasonically processing at 50-60 degrees C for 25-35 minutes, centrifuging, washing, and vacuum drying; and (2) application of composite adsorbent for treating uranium-containing radioactive waste.
