چکیده انگلیسی
This paper examines the possibility of applying ozone (O3) and O3 combined with ultraviolet (UV) to degrade the content of synthetic wastewater Mordant Violet 40 dye (MV-40). The experimental parameters included pH, initial dye concentration and time of reaction; all were assessed in a batch reactor to achieve the optimum operating circumstances. The results obtained showed that the pH and initial MV-40 dye concentration controlled the decolorization process. The maximum decolorization of MV-40 dye solution was obtained at pH 9. More than 98% of color removal was obtained within 20Â min for both UV assisted O3 and individual O3 treatment of 100Â ppm dye concentration. Kinetic analyses showed that the decolorization of MV-40 dye followed the second-order kinetics. The degree of decolorization of MV-40 dye solution was indirectly proportional to the initial dye concentration. Gas Chromatography Mass Spectrum analysis of treated synthetic dye solution was performed at the end of the pre-treatment time to the final degradation products of MV-40 dye. The obtained results explained that the advanced oxidation processes enhanced the biodegradability and lowered the zooplankton toxicity of the treated MV-40 dye solution.
