Using steel slag as a raw material, a new type of adsorption material has been prepared by acid modification method. The preparation conditions of modified steel slag, and the adsorption performance of the modified steel slag for uranium were analyzed by static adsorption method. Results showed that the adsorption efficiency of modified steel slag for uranium was 98.5% under the best condition. In addition, the modified steel slag was also characterized before and after modification by SEM–EDS, BET, FTIR, ICP-OES. The hydroxides and BET of the...
