Fenton oxidation of Reactive Black 5: effect of mixing intensity and reagent addition strategy.

Evaluation of Fenton oxidation process coupled with biological treatment for the removal of reactive black 5 from aqueous solution

Biodegradation of azo dyes is difficult due to their complex structures and low BOD to COD ratios. In the present study, the efficiency of using Fenton's reagent (H2O2 + Fe2+) as a pretreatment process to enhance microbial transformation of reactive black 5 (RB5) in an aqueous system was evaluated. The RB5 with an initial concentration of 250 mg/L was decolorized up to 90% in 60 h by using a ba...

Photochemical Treatment of Amido Black - 10B Waste Water by Photo-Fenton Reagent

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...

Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

بهبود تجزیه پذیری زیستی دی کلروفنل به کمک اکسیداسیون پیشرفته با معرف فنتون

Background and Aim: 2,4-Dichlorophenol (DCP) is a compound  generated in a variety of industrial processes and also by chlorine disinfection of water polluted with phenolic compounds . Dumping of DCP into the environment and water resources is of great concern because of the compound's intense odor and toxicity. DCP is very soluble and resistant to biodegradability so it cannot be removed throu...

Evaluating the Fenton Process Efficiency in Removal of Reactive Red 2 from Aqueous Solution

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...
