Methylene Blue (MB) plays a significant part in the textile, paper, leather and dyeing sectors. However, it causes serious harm to the health of people, animals and plants, thus it is necessary to remove Methylene Blue (MB) dye from dye company wastewater in order to strike a balance between environmental pollution and industry output. The photo degradation process is among the most efficient ways to eliminate more than 90% of Methylene Blue (MB). The high surface area of nanomaterials, however, not only allows for strong dye adsorption on their surfaces, but also for photo catalysis for photo degradation, which adds further value to the removal of Methylene Blue (MB) dye from the wastewater produced by the dye industry. The lack of clean water is one of the problems the world is now facing, hence water purification is essential. In this study, melamine foam decorated by rGO/ZnO nanoparticles has been synthesized and characterized by Raman, SEM, TEM, XRD and UV. XRD and Raman illustrate their synthesis of them. SEM and TEM images achieved the synthesis of rGO nanosheet, ZnO nanoparticles and melamine foam decorated by rGO/ZnO nanoparticles with homogenous distribution without any agglomeration, Photo degradation studies under different conditions of initial dye concentration, irradiation time, pH of the dye solution, catalyst dosage and radiation energy. Photo degradation studies illustrate an increased removal percent of Methylene Blue (MB) by increasing photo catalyst and PH toward alkaline and radiation energy. Melamine foam decorated by rGO/ZnO nanoparticles is the best photo catalyst for Methylene Blue (MB) degradation at pH 11 and a catalyst dosage of 0.0125 mg.
