WebThe present work evaluated the use of photo-Fenton process for the treatment of kraft pulp mill effluent. The photo-Fenton best operating conditions, such as pH, concentration, and H 2O 2: Fe2+ ra-tio were evaluated. The efficiency of the treatment was measured by COD (chemical oxygen de-mand) removal.
WebFeb 15, 2024 · In this study, the treatment of textile industrial wastewater by Fenton and Photo-Fenton oxidation processes was investigated. For this purpose, the pH, Fe 2+ and H 2 O 2 concentrations with the best organic matter and color removal were determined in the Fenton process and comparison with Fenton was made by Photo-Fenton oxidation at the … 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 …
