adsorption capacity were investigated, and adsorption kinetics equations were fitted to determine the adsorption behaviour of uranium on CoFe2O4@rGO in simulated uranium-containing seawater. It was observed that the uranium adsorption capacity of CoFe2O4@rGO composite at pH=5 is 127.6 mg/g, which is 1.31 and 2.43 times that of rGO and pure CoFe2O4. The adsorption process conforms to Langmuir and quasi......
