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 کاملEnhanced Visible Light Photocatalytic Decolorization of Azo Dye using Magnetic PANI/CuFe2O4/ZnO
Semiconductor research has demonstrated the main application in areas such as hydrogen production through photocatalytic water splitting [1], dye sensitized solar cells [2] and photocatalytic treatment of harmful organics from air and water [3]. Developing of efficient visible light responsive photocatalysts for environmental remediation has become the main area in photocatalysis research becau...

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...
متن کاملPhotocatalytic Degradation and Mineralization of Reactive Textile Azo Dye Using Semiconductor Metal Oxide Nano Particles
The textile industry consumes considerable amounts of water during the dying and finishing operations. Dyes extensively used are found to be toxic and considered to be resistant to biodegradation. In this work a detailed investigation of heterogeneous photocatalytic degradation of Navy blue HE2R 1 (NB), azo dye of reactive class is presented using UV/P25TiO2/ZnO2/H2O2 process in aqueous suspens...
