摘要The normal preparation methods of 3D graphene materials such as the solvothermal process and annealing, will inevitably induce the collapse of oxygenated groups. While, the oxygenated moieties, acting as the binding sites for the contaminants and reaction sites of functionalization, are essential and necessary to guarantee the sorption performance of graphene oxide (GO) derivatives. In this study, incorporating assembly and chemical bubble provide a novel strategy to facilely fabricate macroporous 3D GO hydrogel (MGOH). In comparison with the hydrothermal treatment at 60 degrees C, the chemical bubble guaranteed the most retention of oxygenated moieties, and more functional modifications of polyacrylamide. Based on the features, 3D MGOH illuminated the maximum sorption capacity of 25.1 mg g(-1) for As(III) and 74.2 mg g(-1) for As(V), respectively. Benefitting from the average pore width of 26.3 nm and excellent hydrophilicity, the ultraquick sorption equilibriums were realized within 2 min. Overcoming the inherent drawback of arsenic adsorbents, MGOH showed satisfied sorption capacities under neutral condition, especially for As(V). Stable decontamination was also identified via the cycle experiments of MGOH. These results testified the feasibility of incorporating assembly and chemical bubble in the construction of 3D GO hydrogel, and the reliability of 3D MGOH in practical applications.
