Textile dyes pose a major environmental threat due to their toxicity, persistence in water bodies, and resistance conventional wastewater treatment. To address this, researchers have explored biological physicochemical degradation methods, focusing on microbial, photolytic, nanoparticle-mediated approaches, among others. Microbial depends fungi, bacteria, yeasts, algae, utilizing enzymatic pathways involving oxidoreductases like laccases, peroxidases, azoreductases breakdown or modify complex dye molecules. Photolytic employs hydroxyl radical generation electron-hole pair formation, while utilizes titanium dioxide (TiO2), zinc oxide (ZnO), silver (Ag) nanoparticles enhance removal. improve efficiency, microbial consortia been developed decolorization mineralization, offering cost-effective eco-friendly alternative methods. Photocatalytic degradation, particularly using TiO2, harnesses light energy for breakdown. Research advancements focus shifting TiO2 activation from UV visible through doping composite materials, optimizing surface area mesoporosity better adsorption. Nanoparticle-mediated approaches benefit high rapid adsorption, with ongoing improvements synthesis, functionalization, reusability, magnetic nanoparticle integration. These emerging technologies provide sustainable solutions degradation. The primary aim of this review is comprehensively evaluate synthesize current research the azo photolytic processes, nanotechnology-based approaches. also provides detailed information salient mechanistic aspects these efficiencies, advantages, challenges, potential applications industrial contexts.
