چکیده
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 processes. While 200 mg/L, H2O2 100 solution pH 3, temperature 20 °C, a efficiency 82.1% obtained process at 5 mg/L Fe2+, while 2 94.6% obtained. Upon Black, had higher removal than process, even low concentrations. From data various concentrations non-linear method used to determine kinetics Black. Finally, an economic analysis carried out compare differences operating costs between processes.

Oxidation of commercial reactive azo dye aqueous solutions by the photo-Fenton and Fenton-like processes
This paper evaluates the degradation of two azo reactive dyes, C.I. Reactive Yellow 84 (RY84) and C.I. Reactive Red 120 (RR120) by photo-Fenton and Fenton-like oxidation. All experiments were performed on a laboratory scale set-up. The effects of different reaction parameters such as initial pH, contact time, effect of light and hydrogen peroxide concentrations on the oxidation of the dye aqueo...
متن کاملMineralization of hetero bi-functional reactive dye in aqueous solution by Fenton and photo-Fenton reactions.
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...

Herein we report, the robustness of UV/H2O2/Fe2+ system for efficient decolorization of azo-dye Acid Yellow (AY17) solution. It has been found that 88% AY17 decolorized by UV/H2O2/Fe2+ system in 25 minutes under the following optimized conditions; [dye] = 0.14 mM, [H2O2] =1.0 mM, [Fe<s...
متن کاملDecolorization and COD Removal of Reactive Yellow 16 by Fenton Oxidation and Comparison of Dye Removal with Photo Fenton and Sono Fenton Process
Wastewaters from textile industry contain various pollutants including a high content of organic matter, surfactants, additives and dyes. Dyes have obtained notoriety as hazardous substances, because most of them are toxic and considered to be resistant to biodegradation. Recently, advanced oxidation processes (AOP) have received considerable attention because it is possible to degrade organic ...

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...
