Abstract : Fenuron (FRN), a phenylurea herbicide with significant environmental impact, demands reliable and highly selective detection methods. In this work, a novel NCF-LDH/S-rGO nano composite was fabricated on a glassy carbon electrode (GCE) to develop an efficient electrochemical sensor. Structural characterization confirmed successful composite formation, while optimisation of electrochemical parameters enables rapid electron transfer and enhanced redox kinetics. The sensor achieved a broad linear detection range of (0.1–1305 μM), and a low detection limit of 0.011 µM, with appreciable resistance to interference. Validation in real samples, including soil, river water, and grapes, demonstrated reliable recoveries and reproducibility. Overall, the NCF-LDH/S-rGO/GCE platform provides a economical, reliable, and adaptable approach for FRN detection, offering significant promise for environmental surveillance and food safety applications.
