The use of agricultural pesticides in modern agriculture has permitted enormous and reliable production. The organophosphorus pesticide fenitrothion (FT) is widely used in agricultural regions and has been related to detrimental effects on human health. We constructed an electrochemical sensor that detects fenitrothion (FT) using one-dimensional (1D) Pr-2(WO4)(3) nanorods (PWO) incorporated reduced graphene oxide (RGO) electrocatalyst that was synthesized hydrothermally. The PWO nanorods are finely embedded on the RGO nanosheet, according to powder XRD, FESEM, EDS, HRTEM, XPS, and micro-Raman studies. The PWO/RGO electrochemical behavior towards FT was studied by the different electrochemical characterization approaches [CV, DPV, AMP(i-t)]. Our proposed PWO/RGO sensor exhibited a linear range of 0.01-313 mu M and an LOD of 0.0054 mu M in AMP(i-t). The estimation of FT in different water samples proves the usefulness of the PWO/RGO sensor.
