Fenton oxidation technology is the general strategy for the treatment of organic compounds-contained wastewater. However, a considerable amount of ferric sludge was produced during the Fenton process as secondary wastes, which were needed to be further removed from the effluent and treated. In this study, heterogeneous catalysts based on ferrite oxide (Cu-Fe-Ce-O) were synthesized and character...

Submit Manuscript | http://medcraveonline.com the reaction called the Fenton method [1]. Early research on the Fenton reaction was mainly focused on organic synthesis, enzymatic reactions and the cell damage mechanism [2]. It was noted that in the presence of a catalyst, H2O2 can be efficiently decomposed to generate oxidative active substances with strong oxidizing power, and degrade a variety...

Pyrite ash (PA) is created by burning pyrite in the chemical production of sulphuric acid. The high concentration of iron oxide, mostly hematite, present in pyrite ash, gives the basis for its application as a source of catalytic iron in a modified Fenton process for anthraquinone dye reactive blue 4 (RB4) degradation. The effect of various operating variables such as catalyst and oxidant conce...

Abstract An electro-Fenton-like reaction process relying on peroxymonosulfate activation can stably degrade chloramphenicol (CAP) within 16 min, where the kinetic rate constant be as high 0.089 min −1 and energy consumption value low 25.1 kWh•m^ −3 . Evidence indicated that use of a Na 2 SO 4 solution electrolyte enhance CAP degradation due to rapid electron transfer properties. The generated e...

To establish an efficient oxidation process for carbofuran degradation, the effects of some operating parameters such as dosages of H(2)O(2), Fe(2+) and initial carbofuran concentrations were observed during carbofuran degradation by the ultrasound process, Fenton process and a combined ultrasound/Fenton process. The degradation kinetics of carbofuran was also examined based on the experimental...

Trace organic compounds (TrOCs), mostly found in secondary effluents, have a potential impact on the environment, affecting surface water, groundwater, and especially aquatic ecosystems. The present study focuses on oxidation of five selected TrOCs in column experiments, by simulating Soil Aquifer Treatment (SAT) integrated with Fenton-like reaction, using Granular Ferric Hydroxide (GFH) as a c...

There is something intriguing and at the same time fascinating that a simple reaction (of Fe ions with H2O2), which was observed by H.J.H. Fenton over 110 years ago, proves to be very difficult to describe and understand. As yet the nature of the oxidizing species obtained in Fenton reaction is still a subject of deliberation, which may be explained by the fact that it is very common in both ch...

refining oil-contaminated soils has a great importance especially in oil producer countries such as iran. different methods have been provided to eliminate oil contaminations from soil. the aim of this study was to investigate the effect of hydrogen peroxide concentration in refining oil-contaminated soils with fenton chemical method. to do this, a calcareous soil complex sample was collected a...
