Background and Aim: Problems related to conventional Fenton oxidation, including neccesity of having a low pH and production of considerable amounts of sludge, have prompted researchers to consider chelating agents to improve the pH operating range and iron nano-oxide particles to reduce excess sludge. The main objective of this study was to remove pyrene from contaminated soils by a modified F...

Fe2V4O13 is prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-diffuse reflectance spectroscopy (UV-DRS), high resolution scanning electron microscopy (HR-SEM) using energy dispersive X-ray spectroscopy (EDX) analysis. The hetero-Fenton catalyst can be used to mineralize Methyl Orange (MO) under UV-A light. The mineralization rate is influenced by hydr...

We present a novel heterogeneous Fenton-like catalyst of LiFePO4 (LFP). LFP has been widely used as an electrode material of a lithium ion battery, but we observed that commercial LFP (LFP-C) could act as a good Fenton-like catalyst to decompose rhodamine 6G. The catalytic activity of LFP-C microparticles was much higher than a popular catalyst, magnetite nanoparticles. Furthermore, we found th...

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H2O2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. T...

ABSTRACT. In this study, the effect of Fenton and photo-Fenton processes, which are advanced oxidation processes that use hydroxyl radical for decolorization Novacron Black from aqueous solutions, on was investigated. Optimum levels initial pH, temperature, hydrogen peroxide concentration, dyestuff iron concentration were determined. Initial Fe2+ most effective experimental parameters in with p...

several laundry houses throughout tehran consume a large amount of water each day and discharge the resulting wastewater into septic tanks or municipal sewage system without any suitable pretreatment. this would result in severe contamination and other serious environmental issues. in the present study, performance of electrocoagulation/flotation process with aluminum and iron electrodes is com...

Sequential helminth egg inactivation using a solar driven advanced oxidation process (AOP) followed by chlorine was achieved. The photo-assisted Fenton process was tested alone under different H(2)O(2) and/or Fe(II) concentrations to assess its ability to inactivate Ascaris suum eggs. The effect of free chlorine alone was also tested. The lowest egg inactivation results were found using Fe(II) ...

Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this...
