Degradation of Acidic Dyes by Advanced Oxidation Processes
Abstract
This study looks at how acid dyes, often used in the textile industry, break down using advanced oxidation processes (AOPs) like the hydrogen peroxide (H₂O₂) system and the H₂O₂/UV system. The research evaluates the efficiency of these processes in breaking down dye molecules, which reduces their environmental impact when released into wastewater. The H₂O₂/UV system, which combines hydrogen peroxide with ultraviolet light, generates highly reactive hydroxyl radicals that enhance degradation. Researchers analyzed key parameters like dye concentration, pH, reaction time, and the dosage of H₂O₂ to determine optimal conditions for effective dye removal. The results indicate that the H₂O₂/UV system works better at breaking down dyes than using H₂O₂ by itself, making it a good option for cleaning wastewater with industrial dye pollution. This research looks at how Advanced Oxidation Processes (AOPs) can remove and break down acidic dyes in polluted water by examining different factors, like the kind of oxidizing agent used, the pH level, the concentration of the dye, and how long the treatment lasts to make these processes more effective and lessen the environmental harm from pollutants.
