Abstract Adequate wastewater treatment technologies are essential for addressing toxic dyes’ environmental pollution and health hazards. Azo dyes which contain one or more azo bonds widely used in the textile. However, they known to be carcinogenic, mutagenic, highly human health. Traditional treatments methods, such as coagulation, flocculation, biological treatment, often fail eliminate dye molecules due their complex structures strong chemical stability. Therefore, there is a need advanced solutions. Polymer nanocomposites have emerged promising alternative, offering high surface area, tunable properties, exceptional adsorption capacities. This review describes recent reports on synthesis, characterization, application of polymer removal, incorporating key findings remarkable capacity gelatin nanocomposite (950.5 mg/g). most studies were synthetic solutions with limited validation real industrial effluents. paper also future research development scalability, cost analysis, biodegradability practical use. aims guide toward effective adsorbent, eco-friendly, scalable removal.

This study evaluated the influence of electrochemical process application on pollutant removal and changes in characteristics mixed liquor aerobic biological systems used for textile wastewater treatment. For this purpose, samples containing synthetic (nitrogen, phosphorus, acetate, Drimaren Red CL-7B dye) were introduced into bench-scale reactors operated under two experimental conditions: first condition, was performed with a current density 20 A m⁻², using an intermittent exposure mode 6 min / 30 off (Strategy 1 – S1), while second, same applied but continuous 2 S2). control reactor simultaneously comparison purposes, evaluating filterability liquor. The results indicated that processes improved by 35% S1 44% S2. Dye ranged from 40 to 50% reactor, reaching 67% 93% S2 electric current. Regarding increased 30% 96% No significant identified content total suspended solids application. However, exposure, increase approximately observed. It concluded can be promising alternative enhance performance stability treatment
