Pollutants such as pharmaceutical products and pesticides are still present in treated water. Several of these compounds photoactive. The photodegradation eight organic pollutants was studied using listed advanced oxidation processes: UV/H2O2, UV/persulfate, Fenton, photo-Fenton UV/TiO2. results show that is most effective the first 10 min treatments simulated urban wastewater collected from lo...

This study focused on the advanced oxidation of the hetero bi-functional reactive dye Sumifix Supra Yellow 3RF (CI Reactive Yellow 145) using dark Fenton and photo-Fenton conditions in a lab-scale experiment. A 2(3) factorial design was used to evaluate the effects of the three key factors: temperature, Fe(II) and H2O2 concentrations, for a dye concentration of 250 mg L(-1) with chemical oxygen...

background: mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. the treatment of mature landfill leachate by struvite precipitation and fenton oxidation was the main objective of the current research. methods: struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. five initial phs of 3, 4, ...

Oxidation of pollutants in waste water by photo-Fenton reaction has proven an ecofriendly and economical method. Oxidation of amido black – 10B, (an acid dye of azo series) using photoFenton reagent was investigated under ambient conditions. The effect of different parameters like the concentration of ferric ion, amido black10B and hydrogen peroxide, pH, light intensity etc. on the reaction rat...

This paper investigates the elimination of drugs of abuse from six different chemical classes and their metabolites in natural fluvial waters (nearby the output of a sewage system). Mineralization of these substances and toxicological characterization before and after treatment by a heterogeneous photo-Fenton system has been evaluated. This advanced oxidation technology was able to significantl...

This study aimed at comparing various advanced oxidation processes (H2O2, UV, UV/H2O2, Fe /H2O2, UV/Fe /H2O2) for textile dye Reactive Red 195 decolorization. The use of blast furnace dust (BFD) was also investigated as an alternative source of iron in catalytic peroxidation with and without UV radiation. The effects of H2O2 and dye concentrations in kinetics of decolorization were studied. Dec...

This work was aimed at studying the applicability of H2O2-based oxidation processes (namely H2O2/UV, photo-Fenton, and Fenton) for the treatment of six real aqueous wastes. These wastes derived from chemical, pharmaceutical, and detergent production, and were characterised by high COD (chemical oxygen demand) and, in four cases, surfactant concentrations: overall, about 100 tests were conducted...
