Functional group influences on the reactive azo dye decolorization performance by electrochemical oxidation and electro-Fenton technologies
(2017-11-01)
Electrochemical water treatment technologies are highly promising to achieve complete decolorization of dyebath effluents, as demonstrated by several studies reported in the literature. However, these works are focused on ...
Structural and electrochromic study of polypyrrole synthesized with azo and anthraquinone dyes
(Elsevier Science SaLausanneSuíça, 2006)
Ironporphyrin immobilized onto montmorillonite as a bimimetical model for azo dye oxidation
(ELSEVIER SCI LTD, 2008)
In this work, we studied the oxidation of the azo dye Disperse orange 3 (DO3) by hydrogen peroxide, catalyzed by 5,10,15, 20-tetrakis(4-N-methylpyridyl)porphyrin iron(III) chloride immobilized onto montmorillonite K10, ...
Chlorination treatment of aqueous samples reduces, but does not eliminate, the mutagenic effect of the azo dyes Disperse Red 1, Disperse Red 13 and Disperse Orange 1
(Elsevier B.V., 2010-12-21)
The treatment of textile effluents by the conventional method based on activated sludge followed by a chlorination step is not usually an effective method to remove azo dyes, and can generate products more mutagenic than ...
Genotoxicity of textile dye C.I. Disperse Blue 291 in mouse bone marrow
(2019-01-01)
Color Index (C.I.) Disperse Blue 291 (DB291) is an azo dye used by the textile industry. After yarn dyeing, wastewater containing the dye, released into the aquatic environment, may pollute drinking water sources. We ...
Bioremediation of direct dyes in simulated textile effluents by a paramorphogenic form of Aspergillus oryzae
(I W A Publishing, 2012-01-01)
Azo dyes are extensively used for coloring textiles, paper, food, leather, drinks, pharmaceutical products, cosmetics and inks. The textile industry consumes the largest amount of azo dyes, and it is estimated that ...
Evaluation of the Acid Blue 161 dye degradation through electrochemical oxidation combined with microbiological systems
(2019-01-01)
Synthetic textile dyes have considerable molecular complexity, which makes these compounds highly stable and resistant to different types of treatments. Azo dyes represent the most commonly used group of dyes in textile ...
Kinetic, isothermal, and thermodynamic models to evaluate acid blue 161 dye removal using industrial chitosan powder
(2018-03-01)
Textile dyes are often discarded into the environment. Most of them are toxic and their release leads to severe impacts. This study evaluated the potential of industrial chitosan powder as an adsorbent material capable of ...
Toxicity assessment and degradation of disperse azo dyes by photoelectrocatalytic oxidation on Ti/TiO2 nanotubular array electrodes
(Science & Technology Network Inc, 2008-08-31)
The feasibility of photobleaching and detoxification of three disperse azo dyes, namely, Disperse Orange 1, Disperse Red I and Disperse Red 13, in 0.1 mol L-1 Na2SO4 containing anionic surfactant was investigated using ...
