Selective reduction of chlorite to chloride in drinking water by UV/sulfite system: pathways, mechanisms, and kinetics

New Insights into the Mechanism of the UV/Sulfite Process: Formation of SO2•– Radicals and Their Derivatives under Acidic Conditions

“…In recent years, the UV/sulfite process has attracted increasing attention due to its exceptional ability to effectively degrade or remove pollutants from aqueous solutions. − It has been reported that this process can reductively eliminate various contaminants, such as perfluorocarboxylic acids, perfluorooctanoic acid, perfluorooctanesulfonate, per- and polyfluoroalkyl, , monochloroacetic acid, chlorite, bromate, , and metals, etc., thereby demonstrating its significant potential for application.…”
