Study of Sonophotocatalytic Degradation of Acid Red 37 Dye Using MgO/g-C3N4@Zeolite Nanocomposite

This research aimed to study sonophotocatalytic degradation of Reactive Orange 16 dye (RO16) by MgO/g-C3N4@Zeolite nanocomposite. MgO/g-C3N4/Zeolite nanocomposite was synthesized and characterized using the following

X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS) and dot mapping. The synthesized nanocomposite was used as a photocatalyst to degrade RO16 dye aqueous solution. The tests were performed under UV light and ultrasound irradiation. The effect of main factors on the removal of the dye, such as reaction time, solution pH, initial dye concentration, and nanocomposite dosage, were investigated. Results demonstrated that the percentage of dye removal was increased by raising the reaction time, the solution pH, and nanocomposite dosage and decreased by increasing the initial dye concentration. The maximum removal percentage reached 72.36 % at a reaction time of 50 min., pH of 10, initial dye concentration of 10 mg/L, and nanocomposite dosage of 0.25 g/500mL.
