| 英文摘要 | Uranium as the imperative material for sustainable nuclear energy development can be enriched from the natural seawater resources with abundant uranium reserves. Exploration of excellent adsorbents with high adsorption capacity and selectivity has become an urgent task for uranium extraction from seawater. Here, a convenient and environmentally friendly plasma-induced grafting method was employed to accessorily graft amidoxime groups on carbon black (CB-AO) without destruction on the structure of substrate. The plasma treatment on CB surface was conducive to introducing oxygen-containing functional groups for subsequent grafting of organic functional groups. Adsorption behaviors of CB-AO towards uranium under various plasma treatment conditions and solution parameters were investigated. Most importantly, the static and dynamic adsorption experiments in spiked and simulated seawater were also studied, which laid a valuable foundation for subsequent applications in uranium extraction from practical seawater. Thanks to the strong chelating reaction of amidoxime groups with uranium, the CB-AO adsorbent exhibited an outstanding uranium adsorption capacity of 220.95 and 3.2 mg/g in aqueous solution and dynamically simulated seawater, respectively. This work demonstrated the feasibility of the effective plasma-induced grafting method for the fabrication of adsorbents with splendid performance for uranium entrapment from seawater. |
