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...

Background & Aims of the Study: Pharmaceutical compounds have a variety of forms and applications. Specific amounts of toxic organic compounds in the process of their manufacturing and utilization cause environmental pollution problems. So, degradation and removal these compounds are necessary. The aim of this paper is the study photocatalytic degradation of ciprofloxacin drug in aqueous soluti...

A general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. Various oxidation and combined processes such as UV/H2O2/Hypochlorites, Fenton and Electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/UV/ H2O2, coagulation or electro...

Abstract In this study, the Fenton/adsorption of dye effluent containing Levafix blue has been carried out via a cost-efficient and eco-friendly heterogeneous Fenton solar-Fenton methods. Alum sludge, water treatment by-product were successfully collected calcined to 400 °C (AS400) tested for use as catalyst in process. X-ray diffraction, Scanned electron microscopy techniques applied investiga...

This study aimed at comparing various advanced oxidation processes (H2O2, UV, UV/H2O2, Fe /H2O2, UV/Fe /H2O2) for textile dye Reactive Red 195 decolorization. The use of blast furnace dust (BFD) was also investigated as an alternative source of iron in catalytic peroxidation with and without UV radiation. The effects of H2O2 and dye concentrations in kinetics of decolorization were studied. Dec...
