Mesostructured iron oxide/ethylene glycol (FeOx/EG) nanosheets with
an oval shape were created and employed as a magnetic solid-phase
extraction (MSPE) sorbent to extract herbicide chloridazon. Iron oxide
layers are intercalated with deprotonated ethylene glycol molecules to
provide an interlayer gap of 10.6 A. Using scanning electron microscopy
(SEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction
(XRD), thermal gravimetric analysis (TGA), and a vibrating sample
magnetometer (VSM), the size, shape, content, and characteristics of
the produced nanocomposite were determined. The key influencing
factors for extracting chloridazon, such as the volume of the sample, the
amount of sorbent, and the desorption solvent, were optimized. Highperformance liquid chromatography with UV detection was the subject
of analyses. The approach demonstrated strong linearity in the range
of 0.01–100 µg.mL-1, reasonable repeatability (RSD 3.017%, n = 3), and
limits of detection (0.001 µg.mL-1) under the ideal extraction conditions.
