Document Abstract
The management of water pollution in the world is an important need and easy to implement methods are urgently needed for water purification. In this study, efforts were made to assess the efficiency of graphene oxide (GO) as a catalyst in the Fenton process to degrade water pollutants, using the Auramine-O (AM) dye as a model compound. GO was synthesized by the green and direct method using a muffle furnace and was used as a catalyst for dye degradation, along with hydrogen peroxide. The prepared GO was characterized in terms of crystalline properties, morphology and stability using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and thermogravimetric analysis (TGA). Dye degradation was monitored at pH 5. The effect of experimental conditions, i.e., pH, amount of GO, dye and H2O2 on dye degradation was determined. Further, studies were conducted on the reusability of the GO.
