In the current research, the sulfonated metal–organic framework loaded on iron oxide nanoparticles, Fe3O4@MIL100(Fe)-OSO3H, has been synthesized and utilized as a Fenton-like catalyst for the decolorization of aqueous solutions containing methyl orange (MO) dye as a model organic pollutant. The morphology and structure of the catalyst were characterized by X-ray powder diffraction, transmission electron microscopy, Brunauer–Emmett–Teller analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, and UV-Vis diffuse reflectance spectroscopy. The effects of various parameters on MO degradation were investigated and the optimum conditions for MO degradation were found to be an initial concentration of MO of 100 mg/L, initial concentration of H2O2 of 40 mg/L, pH , and microwave power of 500 W. |
