摘要 | A 3D porous carbon foam (CF) loaded with Fe3O4/graphene oxide (GO) has been successfully fabricated. As expected, the saturated adsorption capacity of the resulting Fe3O4/GO-CF composite toward As(iii) can reach up to 111 mg g(-1), superior to those of most of the reported Fe-containing adsorbents. Additionally, the obtained Fe3O4/GO-CF exhibits excellent As(iii) removal performance after five absorption-regeneration cycles with more than 70% of removal efficiency. The exceptional arsenic removal performance can be ascribed to its unique 3D porous network structure as well as fully exposed sorption sites originating from Fe(3)O(4)particles. Finally, the macroscopic size and magnetic feature of the Fe3O4/GO-CF monolith are favorable for facile separation after adsorption. Therefore, the hierarchically porous Fe3O4/GO-CF monolith is highly expected to find many potential applications in arsenic-contaminated water remediation. |
