▎ 摘  要

Air, water, and soil pollution are worldwide problems. Of these, heavy metals and organic dyes are the main targets for removal. Graphene oxide (GO), especially functionalized GO, has shown great application potential for the removal of contaminants from wastewater. This study used Santa Barbara Amorphous-15 (SBA-15) with amino acid to functionalize GO, not only to increase the adsorption sites, but also chelate with heavy metals to improve the adsorption efficiency. The optimal experimental conditions for Cu2+ adsorption were obtained by response surface methodology (RSM): pH=5.8, C-0=38.38 mg/L, M=0.56 g/L, and T=35.68?. The optimum experimental conditions for MB adsorption were pH=10.24, C-0=82.70 mg/L, M=0.33 g/L, and T=35.27?C, and absorption rates all above 70%. Also, the adsorption mechanism, desorption, and reusability of the complexes are reviewed. Finally, the application potential of GO/SBA-15 as an adsorbent in the field of industrial wastewater treatment is summarized and its prospects are discussed.
