الوصف: | The composite sponge of Hawaii nut shell biochar and graphene oxide was prepared by using polyvinyl alcohol as three-dimensional composite carrier (BC/GO/PVA). The characterization analysis found that the composite sponge material has a good specific surface area of pore structure, and improved the plasticity of biochar, overcoming the stacking problem of graphene sheets, and proposed a reasonable material cross-linking composite mechanism. The optimum adsorption capacity and adsorption mechanism were analyzed by batch adsorption experiments. The results showed that the removal of uranium by BC/GO/PVA materials was beneficial under weakly acidic conditions. The maximum adsorption capacity of the experiment is 14.3 mg/g. |
