▎ 摘  要

In the present work, graphene oxide (GO) is synthesized successfully by the Hummer method. The product is characterized by various techniques such as scanning electron microscopy, Fourier transform infrared, X-ray diffraction, and UV-vis spectroscopy. The prepared GO is used as a novel absorbent to remove different dyes, organic, and inorganic pollutants from real textile wastewater. The effects of operational parameters like absorbent dosage (13-25 mg), pH (3-9), and contact time (12-30 min) on wastewater treatment are studied by response surface methodology. The optimized parameters are found to be 25 mg for GO dosage, pH 8, and 25 min for contact time. The chemical oxygen demand removal efficiency is calculated 62.10% under optimum conditions. These results suggest that the GO nanoparticles are a good candidate for the rapid remove of dyes and complicated pollutants from aqueous solutions.
