Green Nanocomposite for the Adsorption of Toxic Dyes Removal from Colored Waters

The discharge of dyes from textile industries led to a broad range toxicological and environmental effects, posing severe health issues for humans animals worldwide. These are highly stable and, if not adequately treated, remain in the environment extended periods. Adsorption, most efficient cost-effective method, offers unique advantages using natural adsorbents, such as marble waste composites, dye removal. easy availability waste, its low cost, eco-friendly nature, ease operation, simplicity design, flexibility, great affinity make it suitable option Golden nanocomposites prepared results studies suggested that treated golden composite materials exhibit better adsorption efficiency (224.8, 299.5, 369.2 mg/g) adsorptive removal than untreated (114.4 mg/g). This research also used isothermic kinetic models evaluate effects numerous parameters, example, initial concentration, pH, time, temperature, adsorbent dose. highest 369.9 mg/g was achieved during present study blue at an optimized pH 7 temperature 30 °C. It observed composites gave R2 (0.99) values second-order kinetics model. Results obtained comparing Langmuir, Freundlich, Temkin, Dubinin, Herkin Jura isotherms showed Langmuir isotherm Foron red (0.97), Temkin (0.98), Freundlich black (0.97) fit on both composites. Characterization techniques, scanning electron microscopy (SEM) Fourier transform infrared spectroscopy (FTIR), discussed structural determination
