In this work, the efficiency of a photo-electrochemical method to remove color in textile dyeing effluents is discussed. The decolorization of a synthetic effluent containing a bi-functional reactive dye was carried out by applying an electrochemical treatment at different intensities (2 A, 5 A and 10 A), followed by ultraviolet irradiation. The combination of both treatments was optimized. The...

The reuse of effluent water is one the main challenges to achieve a more sustainable development. Dyes from textile industry can percolate, contaminate soils and affect courses. Advanced Oxidative Processes (AOP), such as heterogeneous photocatalysis with UV light radiation metallic nanoparticles, generate reactive oxygen species hydroxyl radicals that reduce pollutants. This work synthesized z...

Currently, the reduction of reactive dyes present in the textile effluent is a big challenge due to the threat to the environment. Existing physical and chemical methods contains many drawbacks. In the present scenario microbial reduction pays much attention and current focus of research. Therefore, the present study isolated dye decolorizing bacterium Exiguiobacterium aurantiacum (TSL7) from a...

Reactive dye is one of the most applicable dyes in textile industries which its release to the water bodies creates a concern for environmentalists. Here, in this data article a bone-char (BC) ash decorated with MgO-FeNO3 for removing reactive black 5 (RB5) dye in a catalytic ozonation process (COP) system. Operational parameters data such as initial RB5 concentration, pH, catalyst dosage, and ...

This paper reports application of cetyltrimethylammonium bromide (CTAB) coated magnetite nanoparticles (Fe3O4 NPs) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was investig...

Abstract Textile effluents being one of the major reasons for water pollution raises concern bodies and habitation surrounding them. The lack biologically safer treatment solutions creates a disposal these effluents. present study focuses on degradation textile dyes using leaf extract Artemisia stelleriana-assisted nanoparticles zinc oxide (ZnO-NPs). ZnO NPs synthesized were confirmed spectrosc...

Azo dyes in textiles may release aromatic amines after enzymatic cleavage by skin bacteria or after dermal absorption and metabolism in the human body. From the 896 azo dyes with known chemical structure in the available textile dyes database, 426 azo dyes (48%) can generate one or more of the 22 regulated aromatic amines in the European Union in Annex XVII of REACH. Another 470 azo dyes (52%) ...
