Peracetic Acid Activated with Electro-Fe2+ Process for Dye Removal in Water
نویسندگان
چکیده
An electro-Fe2+-activated peracetic acid (EC/Fe2+/PAA) process was established for organic dye removal in water. The operation factors such as the PAA dosage, Fe2+ amount, current density, and pH were investigated on methylene blue (MB) synergistic EC/Fe2+/PAA system. Efficient MB decolorization (98.97% 0.06992 min−1) achieved within 30 min under 5.4 mmol L−1 PAA, μmol Fe2+, 15 mA cm−2 intensity, 2.9. Masking tests affirmed that dominating radicals hydroxyl (OH), (CH3CO2·, CH3CO3·), singlet oxygen (1O2), which generated from activated by synergetic effect of EC Fe2+. influence inorganic ions natural matter determined. Moreover, efficacy confirmed decontaminating other pollutants, antibiotic tetracycline metronidazole. studied synergy offers a novel, advanced oxidation method activation wastewater treatment.

Potentially harmful disinfection byproducts (DBPs), as a significant challenge in water treatment, are formed when oxidizing disinfectants react with natural organic matters (NOM). Unfortunately, an unwanted side effect is the formation of harmful by-products, such as THMs and HAAs, following the chlorination stage. DBPs cause a variety of diseases like cancer in humans. In this ...
