“…A reação Fenton utiliza a decomposição catalítica do peróxido de hidrogênio por íons ferrosos em meio ácido com a finalidade de produzir radicais hidroxila ( • OH) (SUN et al, 2007), sendo esta espécie a principal responsável pela eficiência na degradação de poluentes. O • OH é caracterizado por possuir um elevado potencial de oxidação, provocando a quebra de moléculas poluidoras e gerando compostos quimicamente mais simples, podendo levar, em certos casos, até a mineralização (CO 2 , H 2 O) (HSING et al, 2007;OTURAN et al, 2008).…”

The process of advanced oxidation by Fenton reaction (Fe 2+ /H 2 O 2 ) was studied in this work for decolorization of two synthetic effluents, containing the dyes Methylene Blue (MB) and Rhodamine B (RB).Experimentally, solutions at concentrations of 10 mg L -1 of the dyes were exposed to different concentrations of the oxidizing agent (H 2 O 2 ) and catalyst (Fe 2+ ) at a temperature of 27 °C and pH 3. The results showed high levels of color removal, with efficiency of 96% for MB and 86% RB.The data showed good adjustment to the kinetic model. The monitoring of the absorption spectrum of the dyes showed a reduction in amplitude of the peaks related to the chromophoric groups in both compounds, confirming the levels of efficiency achieved. The analysis of removal of organic matter in terms of Chemical Oxygen Demand (COD) did not follow the same rate of decrease of decoloration, resulting in reductions of 40.9% for MB and 25.5% for the RB.

“…As a result, a large amount of sodium and chloride ions are present in textile wastewater, which increases the toxicity of water sources (Ali et al, 2006;Paul et al, 2012;Dey and Islam, 2015). The color of the effluent measured as absorbance was highly visible, which may have environmental concerns including aesthetic problems (Sun et al, 2009;Modi et al, 2010;Lu et al, 2010;Holkar et al, 2016).…”

Wastewater from textile processing and dyestuff manufacturing industries contains different kinds of dyes and their metabolites, which are mutagenic and carcinogenic in nature. Such wastewater should be treated in order to avoid ground and surface water contamination. The aim of present research was to isolate such bacterial strains which are capable of degrading dye-originated aromatic amines. Ten samples of wastewater and sludge were collected from outlets and wastewater streams of different textile industries. The analysis of wastewater showed a wide variation in the pH (8.10-12.3), total dissolved solids (500-20100 mg L ) using 10 mL wastewater/sludge as inoculum source. Based on ability to degrade 4-nitroaniline most efficient bacterial strain was identified as Raoultella planticola (IL11) through 16S rRNA gene analysis. These findings suggest that the indigenous bacterial strains have potential for bioremediation of dye-containing textile effluents, and for complete mineralization, 4-nitroaniline degrading strains may be used in combination with dye degrading strains.

“…The COD removal increased from 13% to 90% as the temperature increased from 40 to 60°C. That's because the elevated temperature can increase the reaction rate of hydrogen peroxide and catalysts, thereby increasing the production rate of hydroxyl radicals or high-valence copper species [10]. Furthermore, increasing temperature makes the reactant molecules have more energy to overcome the activation energy of the reaction [11].…”

Abstract. Silica-supported copper catalyst materials have been synthesized via an incipient wetness impregnation. The resulting samples were characterized using X-ray diffraction (XRD) and Scanning electron microscope (SEM). The heterogeneous Fenton-like oxidation of reactive azo dye solutions by this catalyst was also investigated. The effects of various operating conditions on decolorization performance were evaluated, namely hydrogen peroxide dosage, initial pH, catalyst loading and initial dye concentration. The results indicated that by using 34 mmol/L of H 2 O 2 and 6.0 g L -1 of the catalyst at 60 o C, pH 3.5, 97% of decolorization efficiency was achieved within 90 min. CuO/SiO 2 hollow sphere is shown a promising catalyst for degradation of azo dye aqueous solution by Fenton-like processes.
