Web本文综述了Fe0参与的类Fenton试剂氧化反应降解废水中有机污染物的研究进展，期望为后续相关研究提供帮助。 1 Fe0-H2O2体系. 在Fe0-H2O2体系的研究中，常以废铁屑作为Fenton试剂氧化反应的Fe2+来源，通过以废治废降低处理成本。该法通常被称作铁屑法。 WebJul 15, 2016 · Photo-Fenton, which utilizes UV irradiation in combination with the Fenton reaction, is used to reduce ferric ions , . We also utilized a ferrioxalate-mediated photo-Fenton process to aid Fe 3+ reduction . Recently, application of electrochemical AOPs based on Fenton’s reaction chemistry (EAOPs-Fenton) has received much attention.
WebDegradation and mineralization of sulfamethoxazole by the photo-Fenton reaction (Fe2+/H 2 O 2 /UV) were investigated. It was found that 176 mg• L-1 sulfamethoxazole was … WebMay 1, 2008 · This alternative (UV/Fe 2+ /H 2 O 2) is known as photo-Fenton. UV radiation leads to faster regeneration of Fe 2+ ions in the solution. Fe 3+ complexes are photoreactive and its photolysis generates Fe 2+ ions in acidic conditions [31]. Photo-Fenton experiments led to the maximum reduction of COD. A 59% of COD removal was obtained using 5000 …
