Innovative Approaches for Removing Reactive Yellow 145 Dye Pollutants from Water Sources

Abstract

The escalating challenge of industrial dye pollution in wastewater necessitates the exploration of effective treatment methodologies. This study introduces a novel approach combining microwave irradiation with the Fenton oxidation process, showcasing a significant leap in the removal of Reactive Yellow 145 pollutants. By systematically manipulating variables such as Reactive Yellow 145 concentration, catalyst presence, and reaction environment pH, the investigation reveals a substantial increase in the degradation efficiency of complex dye molecules. The synergy between microwave energy and chemical oxidants under optimal conditions results in a remarkable reduction of both color and chemical oxygen demand (COD) levels, with the process achieving over 95% dye elimination and 82% COD reduction within 7 minutes. The analysis of UV-Vis spectroscopy before and after treatment showed that the microwave-enhanced Fenton process efficiently decomposed dye molecules, with a notably faster decomposition rate observed for azo and hydrazine groups compared to aromatic structures. This study not only underlines the potential of microwave-assisted Fenton processes in addressing persistent wastewater contaminants but also sets the groundwork for future research in scalable, environmentally friendly wastewater treatment solutions.
