Proficient Adsorption Investigations of Methylene Blue Dye Utilizing Incorporated Mg-Doped CuO Nanoparticles: An Inventive Methodology for Powerful Methylene Blue Dye Treatment

The growing contamination of water sources worldwide necessitates urgent interventions to ensure access to clean drinking water. Among the diverse pollutants, the discharge of dyes into water bodies presents a formidable environmental concern. Traditional wastewater treatment methods often fall short in addressing the persistence and toxicity of these contaminants, emphasizing the need for innovative approaches. In this study, we synthesized Mg-doped CuO nanoparticles using a co-precipitation method and characterized their chemical properties. The nanoparticles exhibited exceptional adsorption capabilities for various dye compounds, holding significant potential for wastewater remediation. Specifically, we investigated the removal of synthetic dyes using these metal-doped nanoparticles. Optimal parameters for maximal dye removal were determined through comprehensive experimentation, including adsorbent dosage, initial dye concentration, contact time, and temperature. Our results indicated that basic dye (Methylene Blue) demonstrated maximal adsorption at pH 5, with Mg-doped CuO nanoparticles exhibiting a superior adsorption capacity of 42.15 mg/g under optimized conditions (pH 5, 0.1 g/50 mL dosage, 120 minutes contact time, and 200 ppm dye concentration). Overall, our findings highlight the potential of Mg-doped CuO nanoparticles as an innovative and efficient solution for dye removal in wastewater treatment, offering a promising avenue for mitigating water pollution challenges.
