Fenton reaction system
WebOct 21, 2024 · The Fenton reaction is one of the most effective AOPs; it uses soluble iron salts and hydrogen peroxide to generate highly reactive hydroxyl radicals. ... This confirms that the system behaves similarly to the Fenton’s reaction, where a source of iron and H 2 O 2 is required to form the highly reactive hydroxyl (•OH) free radicals. WebIn this work, the efficiency of ultrasound, Fenton, and ultrasound-Fenton (US-Fenton) processes were evaluated separately for the treatment of municipal activated sludge (MAS). Additionally, the effects of operational parameters such as pH, hydrogen peroxide and ferrous iron concentrations, and cavitation time were studied. During the experiments, …
