  "abstract": "Green nanomaterials have attracted considerable attention for environmental monitoring due to their sustainability and multifunctional properties. In this study, copper oxide nanoparticles were synthesized using pomegranate peel (pp) extract (CuO@PP) as a reducing and stabilizing agent and investigated for both electrochemical detection and adsorptive removal of tetracycline. The synthesized CuO@PP nanoparticles were characterized by UV–Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). CuO@PP nanoparticles were immobilized onto a screen-printed electrode for electrochemical detection of tetracycline. Square wave voltammetry (SWV) showed good analytical performance, with a low detection limit of 3.1 nM, good selectivity, and successful application in real-water samples, including untreated tap water and hospital wastewater. In addition, CuO@PP showed effective tetracycline adsorption, reaching 88% removal within 25 min. The Langmuir model gave an estimated maximum adsorption capacity of 312.77 mg g−1, while the Freundlich model provided a better fit to the experimental data, indicating adsorption on a heterogeneous surface. These results demonstrate the potential of green-synthesized CuO@PP as a multifunctional material for both tetracycline detection and removal, with promising applications in environmental monitoring and water treatment.",
