Özet
Mancozeb (MCZ) is a widely used fungicide whose excessive application concerns due to crop and water contamination which posing risks to environmental and human health. Therefore, sensitive and selective detection of MCZ is essential for food safety and environmental monitoring. In this study, a porous nickel glycerolate (Ni-Gly) material was synthesized via cost-effective and eco-friendly solvothermal method and characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, and X-ray absorption fine structure (XAFS) techniques. The synthesized material was employed to fabricate a nickel glycerolate-modified screen-printed carbon electrode (Ni-Gly/SPCE) for voltammetric determination of MCZ. Electrochemical performance was evaluated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Under optimized conditions, the developed sensor exhibited a wide linear dynamic range (0.5–60 µM) with low detection limit 0.028 µM and sensitivity (0.73 µA/µM/cm²). The sensor was successfully applied to detect MCZ residues in orange, kiwi, and apple food samples, achieving recoveries between 97.2% and 102.6% which confirming its practical applicability for food safety analysis.
