“…Certain azo dyes degrade over time, releasing substances known as aromatic amines, some of which are carcinogenic. [9][10] They are easily absorbed when in contact with the skin, entering the body and causing DNA damage in humans. 11 One of the most critical contaminants is synthetic colorants.…”

The existence of colorants in water has caused many disadvantages to aquatic systems and the environment. Scientists have made efforts to decompose and remove them using many different methods. In this study, Cu2O nanoparticles were synthesized with a mixture of reducing agents, including glucose and ascorbic acid, as a photocatalyst for decomposing azo dyes. The prepared nano Cu2O was fully characterized using scanning electron microscope (SEM) imaging, X-ray diffraction (XRD) diffraction measurements, and band gap energy determination. The obtained nano Cu2O was of a uniform truncated block shape with particle size ranging from 50 to 150 nm. The prepared nano Cu2O showed remarkable photocatalytic behavior toward methyl orange under visible light radiation with the removal percentage of 95.46% after 4 hours of reaction. In addition, the catalyst can be reused many times without much impact on catalytic efficiency. Photocatalytic degradation using Cu2O nanoparticles is a promising method for the removal of methyl orange, contributing to creating a safe and sustainable environment.

“…In addition, most chemical dyes have various drawbacks that seriously affect human health. Indeed, azo dyes enter the body through ingestion and cause cancer and DNA diseases [7,8].Some of the chemicals in TWW including dyes are recalcitrant in nature because of their stability in front of the washing processes and therefore required treatment by appropriate and effective methods prior to their release into the environment. Physical methods such as coagulation, flocculation, and filtration, chemical oxidation by oxidizing agents such as O 3 and H 2 O 2 , advanced oxidation techniques such as photocatalytic oxidation and fenton, and biological methods using microorganisms such as fungi, algae, and bacteria [9][10][11] are the main treatment strategies explored to date.…”

The treatment of textile wastewater (TWW) loaded with recalcitrant azo dyes in bioelectrochemical systems (BES) rather than in physicochemical processes is a low-cost and environmentally friendly process. The main objective of this study is to investigate the potential of different saline sediments collected from extreme Tunisian environments for the formation of bioanodes capable ofsimultaneous azo dyes degradation and electric current generation in synthetic (STWW) and real textile wastewaters (RTWW) characterized by a varied composition of azo dyes and a high salinity. The obtained bioanodes and anolytes were studied comparatively by electrochemical, microscopic, analytical, and molecular tools.Based on the UV–visible spectra analysis, the breakdown of the azo bond was confirmed. With RTWW, the BES achieved a chemical oxygen demand (COD) abatement rate of 85%with a current density of 2.5 A/m2. Microbial community analysis indicated that a diverse community of bacteria was active for effluent treatment coupled with energy production. At the phylum level, the electrodes were primarily colonized by proteobacteria and firmicutes, which are the two phyla most involved in bioremediation. The analysis of the microbial community also showed the abundance of Marinobacter hydrocarbonoclasticus and Marinobacter sp. species characterized by their high metabolic capacity, tolerance to extremophilic conditions, and role in hydrocarbon degradation.
