Abstract :Copper oxide nanoparticles insert ignore into journalissuearticles values(CuO NPs); were produced using green synthesis method with Cimin grape extract insert ignore into journalissuearticles values(Vitis vinifera cv.);. The produced CuO NPs were used to remove methylene blue insert ignore into journalissuearticles values(MB); from water by degradation with Fenton-like reactions. The surface properties of the CuO NPs were determined by FT-IR, SEM and XRD techniques. Experimental parameters for MB removal were selected as: pH: 3 – 11; Temp: 20 - 80°C; initial MB concentration insert ignore into journalissuearticles values(15 - 50 ml-1);, and CuO NPs concentrations insert ignore into journalissuearticles values(25 - 800 mg ml-1);. The best reaction conditions were found to be pH: 7 - 11, temperature: 40 - 45C, interaction time: 120 min, initial MB concentration: 3.125 mg ml-1 and CuO NPs concentration: 25 mg ml-1. Under these conditions, CuO NPs showed a 97.80% efficacy for the removal of MB from wastewater with Fenton-like process. Moreover, this study showed that reagents were reusable, inexpensive, biocompatible, easy to prepare, harmless insert ignore into journalissuearticles values(CuO NPs, H2O2);, and Fenton-like reaction conditions were created.
