Fluorescence Sensor Based on Polyaniline Supported Ag-ZnO Nanocomposite for Malathion Detection

Sensitive and selective determination of harmful organophosphate is rigorously fundamental due to its large negative influence on the environment human health. Ultrasensitive fluorescence nanocomposite was developed for malathion detection which based electrostatic interaction between polyaniline Ag-ZnO nanocomposite. The (Ag-ZnO/PANI) prepared via sol-gel technique next in situ oxidative polymerization polyaniline. synthesized characterized by FT-IR, XRD, SEM, UV-vis, spectroscopic techniques. intensity quenched MA, proportional concentration MA range 0–1000 nM, with a limit 13.2 nM. proposed method sensitive, selective, easy design, fast operation. Therefore, it has been effectively used agricultural products suitable recovery.
