This study makes a comparison between Fenton, Fenton-like, photo-Fenton and photo-Fenton-like treatment methods to investigate the removal of two acid dyes. The two selected acid dyes are C.I. Acid Orange 8 (AO8) and C.I. Acid Red 17 (AR17). These were chosen as model organic contaminants. The effect of operating parameters, such as amount of Fenton’s reagent (H2O2 and Fe) and Fenton’s-like rea...

The purpose of this study is to investigate the chemical degradation of the organophosphorus pesticide of parathion and carbamate insecticide of methomyl in the aqueous phase through Fenton process. With the employment of batch Fenton process, the degradation of the two selected pesticides at different pH, initial concentration, humic acid concentration, and Fenton reagent dosages was explored....

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...

Advanced oxidation processes like Fenton and photo-Fenton have been effectively applied to oxidize the persistent organic compounds in solid waste leachate and convert them to unharmful materials and products. However, there are limited data about application of Fenton-like process in leachate treatment. Therefore, this study was designed with the objective of treating municipal landfill leacha...

Cosmetic industry wastewater is high strength wastewater and it can be difficult to decompose with biological treatment due to its high stability or toxicity. The use of Fenton reagent as a Chemical pretreatment was investigated with a Factorial Experiment where the concentrations of ferrous sulfate, hydrogen peroxide and reaction duration was the main parameters examined for COD and TOC reduct...

A simple and sensitive electrochemical biosensor was used to detect tyrosine oxidation induced by hydroxyl radicals generated by Fenton reaction (Fe(2+)/H(2)O(2)). Poly(glu, tyr) (4:1) peptides were immobilized on indium tin oxide (ITO) electrode surface via layer-by-layer assembly technique, and Os(bpy)(3)(2+)-mediated tyrosine oxidation current was employed as the signal reporter of the biose...

Many types of advanced oxidation processes (AOPs), namely Fenton (Fe 2+ /H2O2) with different doses, Fenton-like (UV/Fe 2+ /H2O2), photo-Fenton (Fe 2+ /H2O2/TiO2), and plasma technology have been investigated for the removal of organic matters (COD content) from landfill leachate. Fenton's oxidation was the most effective as the most effective ratio 1/10 (Fe 2+ /H2O2) which allow the COD remova...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...

Volume 3 • Issue 2 • 1000124 afflict smokers [2]. There has been suggestion that oxidative damage caused by accumulation of Fenton reagents (iron and copper) in the lens can cause lens damage and possibly cataract [3]. The lenses of experimental animals (Wistar rats) showed significantly decreased zinc and increased iron, and calcium concentration relative to those of sham exposed controls. How...

Textile wastewater contains a number of dyes which are known to be toxic and carcinogenic. In this study the results show that the Fenton (Fe2+/H2O2) process is an efficient method for the removal of Acid Brown 14 (A.BR14) and Cationic Blue 41 (C.B41) dyes from textile wastewater. In this method, two reagents Fe2+and H2O2 are used and do not require any additional energy. Several experiment...
