Abstract :Copper oxide nanoparticles (CuO NPs) were produced using green synthesis method with Cimin grape extract (Vitis vinifera cv.). The produced CuO NPs were used to remove methylene blue (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 (15 - 50 ml-1), and CuO NPs concentrations (25 - 800 mg ml-1). The best reaction conditions were found to be pH: 7 - 11, temperature: 40 - 45C, 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 (CuO NPs, H2O2), and Fenton-like reaction conditions were created.Keywords : Copper oxide nanoparticles, fenton-like, methylene blue, degradation, removal
