Abstract Dye wastewater is becoming one of the most significant sources water pollution, and its impact on human survival immeasurable. In this study, we successfully synthesized a nanofiber membrane with environmentally friendly efficient properties using electrospinning mixture sodium alginate (SA) copper oxide (CuO) nanoparticles, aimed at effective dye removal. The adsorption performance SA/CuO was evaluated cationic methylene blue (MB). maximum capacity increased significantly addition CuO reaching value 1633.4 mg g −1 , almost twice as much that pure SA membrane. kinetics follows pseudo‐second‐order model, where chemisorption acts rate‐limiting step. isotherm data indicate monolayer. nanofibrous membranes showed better removal under an alkaline environment. After four cycles adsorption/desorption, MB efficiency remained 70.1% original capacity. nanoparticles facilitated dyes, while form easily recoverable reusable. Therefore, as‐prepared composite potentially favorable adsorbent material for treatment applications.
