Application of ecofriendly magnetic nanocomposite synthesized from natural materials for separation and determination of diazinon pesticide in real water samples

In this study, a cheap, novel, ecofriendly and effective nanosorbent was synthesised with natural materials such as sand beach eggshell for diazinon determination in water. The successfully characterised using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), energy dispersive (EDX), field emission scanning- electron microscopy (SEM), vibrating sample magnetometer (VSM) Brunauer–Emmett–Teller (BET) methods. Effective parameters were optimised the extraction of done by UV-Vis at 248 nm. method linear range 50–400 µg L?1 limit detection 6.9 L?1. Adsorption kinetic isotherm studies performed.
