In this study the residue behavior of toxic insecticide abamectin on surface water with fluorescent chemical sensors because they are non-destructive, the ability to show decomposed concentrations, fast response, and high was investigated. In this research, a chemical sensor was synthesized PbS functionalized with gelatin quantum dots for toxic abamectin. The calibration curve was linear in the range of (0.05 to 10.0 µgL−1). The standard deviation of less than (1.1 %), and detection limits of the method (0.05 µgL−1) in time 60 s, 350 nm were obtained for sensor level response PbS Quantum Dot–Gelatin nanocomposites sensor with (95%), confidence evaluated. The observed outcomes confirmed the suitability recovery and a very low detection limit for measuring the toxic abamectin. The chemical PbS Quantum Dot–Gelatin nanocomposites sensor as excellent sensor in the practical application of toxic abamectin related to residue management is in Water Samples. The method fluorometric can be used as to estimate the appropriate PHIs and can also support authorization of plant protection products as supplementary information.

In this current article, a chemical sensor was synthesized PbS functionalized with Gelatin Quantum Dots for Fenpyroximate. 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.
