Outline
To establish a rapid detection method for the residue of the fungicide hexaconazole in food by dispersive liquid-liquid microextraction-high performance liquid chromatography.
A deep eutectic solvent synthesized from fenchyl alcohol, hexanoic acid and acetic acid at a molar ratio of 1:3:4 was used as the supporting solvent to prepare a ferrofluid with self-dispersibility and magnetic responsiveness by incorporating Fe3O4 nanoparticles. The prepared ferrofluid served as the extraction solvent for dispersive liquid–liquid microextraction, and hexaconazole was subsequently separated and quantified by high-performance liquid chromatography.
Under the optimal experimental conditions, the detection linear range of this method for hexaconazole was 0.02–2.00 μg/mL, the limit of detection was 0.006 μg/mL, and the relative standard deviation was less than or equal to 8.2%. The recovery rates of samples added to mineral water, tea and fruit juice were 83.9% to 95.6%.
This method is environmental friendly, easy to operate and highly sensitive. It can be effectively applied to the rapid detection of pesticide residues in food, providing a new and effective technical means for food safety testing.
