The measure of Fenpyroximate was performed using concentration (2.5×10-3 mol L-1), PbS Quantum Dot-Gelatin nanocomposites sensor, pH 6, and time 40 s, wavelength 328 nm. Under the optimum conditions, the detection limit linear range were obtained (0.02 to 20.0 µg L-1). The standard deviation of less than (2.0%), and detection limits (3S/m) of the method (0.02 µg L-1) for determination of Fenpyroximate, was obtained. The observed outcomes confirmed the suitability recovery and a very low detection limit for measuring the Fenpyroximate. The chemical PbS Quantum Dot–Gelatin nanocomposites sensor as excellent sensor in the practical application of Fenpyroximate related to residue management is in surface water samples.
