Abstract
Graphene oxide (GO) has become a popular material due to its valuable properties and wide range of applications in various fields. GO was synthesized using a modified Hummers’ method and characterized through various techniques, including X-ray diffraction (XRD), and scanning electron microscopy (SEM), The effectiveness of GO in decolorizing methyl orange was assessed using UV-Vis spectrophotometry, with varying GO concentrations (0.05, 0.075, 0.1, 0.15) g and time (2–120 minutes) intervals. The study demonstrated that GO effectively adsorbs and removes MO from aqueous solutions. Specifically, at a GO concentration of 0.15 g, a 90.14% reduction in MO absorbance was observed after only 10 minutes, whereas at 0.05 g, 0.075 g, and 0.1 g GO, the reductions were 58.38% and 71.65%, and 80.61, respectively. At 120 minutes adsorption efficiency of 0.15 g is 99.57%. At 120 minutes the color of MO had become completely transparent. These results highlight the potential of GO as a highly efficient material for dye removal and provide insights into optimizing its use for environmental remediation applications.
