| In this study, a green mode of solidification of floating organic droplet–based dispersive liquid–liquid microextraction has been developed for the extraction of 16 polycyclic aromatic hydrocarbons from honey samples before their determination by gas
chromatography–mass spectrometry. In this method, an appropriate volume of menthol:decanoic acid deep eutectic solvent (as an extraction solvent) is added on a sugar
cube (as a disperser agent). In the following, the cube is released into the diluted
honey sample placed in a tube. After manual shaking a cloudy state is obtained as
a result of dispersing the extraction solvent droplets throughout the sample solution
and the analytes are extracted into them. After placing the tube in an ice bath, the
droplet of the extractant is solidified on the top of the solution. This drop is taken and
after dissolving in acetonitrile, an aliquot of the solution is injected into the separation system. Under optimum conditions, the suggested approach had high extraction
recoveries (76–93%) and enrichment factors (380–465), low limits of detection (14–
52 ng/kg) and quantification (47–173 ng/kg), and satisfactory repeatability (relative
standard deviation ≤ 9%). |
