Fluorescent Method for Determination of residue toxic Insecticide Abamectin Using PbS Quantum Dots-Based Gelatin in Water Samples

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.
