NOVELTY - Preparing nucleus uranium removal adsorbent involves preparaing graphene oxide by mixing 2-6 gram graphite, 1-4 gram sodium nitrate, and 85-120 ml sulfuric acid in a beaker and placing in an ice bath, slowly adding 9-15 gram potassium permagnate under continuous stirring, and controlling addition speed to ensure that the temperature of the reaction liquid is not higher than 20 degrees C until the components are completely mixed, removing the ice bath, the temperature of the solution is raised to 30-40 degrees C for 30 minutes, adding 160-200 ml of water, stirring for 30 minutes. 300-500 ml of a solution having hydrogen peroxide concentration of 0.05 wt.% added. The reaction is terminated. The product is a yellow-brown solid, which is centrifuged in a centrifuge and then washed with a concentration of 10% HCL and deionized water for multiple times. USE - Method for preparing nucleus uranium removal adsorbent. ADVANTAGE - The method enables to prepare nucleus uranium removal adsorbent which realizes minimizing of radioactive waste. DETAILED DESCRIPTION - The vacuum environment is used for drying at 40 degrees C to obtain graphene oxide GO, washed the waste tea TW with deionized water multiple times to removed dirt, then boiled in deionized water at 80 degrees C for 1 hours to removed colored and soluble components, then washed with deionized water until colorless, at 100 degrees C dried in an oven, pulverized the obtained product into a powder, and set aside, mixed graphene oxide GO and spare waste tea TW powder in deionized water according to mass ratio 1:1, sonicated for 3 hours, using solid-liquid separation by centrifuge. The separated solid is washed multiple times with deionized water and ethanol, and dried in a vacuum atmosphere at 50 degrees C to obtain final product.
