- Abstract
In the present research, an ultrasound‐assisted magnetic solid‐phase extraction coupled with a gas chromatography‐mass spectrometry hybrid system was developed for the extraction/determination of trace amounts of polycyclic aromatic hydrocarbons in high‐consumption soft drinks and non‐alcoholic beers in Iran using magnetite graphene oxide adsorbent. The magnetite graphene oxide was characterized by scanning electron microscope, transmission electron microscopy, Fourier‐transform infrared spectroscopy, X‐ray diffraction, and vibrating‐sample magnetometer techniques. The highest extraction recovery (73.05%–95.56%) and enrichment factor (90.65–106.38) were obtained at adsorbent mass: 10 mg, adsorption time: 30 min, salt addition: sodium chloride 10% w/v, desorption time: 20 min, eluent type: hexane: acetone (1:1, v/v), and desorption solvent volumes: 200 μl. Under optimum conditions, the linearity range for polycyclic aromatic hydrocarbons determination was 0.2–200 ng/ml with a coefficient of determination > 0.993, the limit of detection = 0.09–0.21 ng/ml, the limit of quantitation = 0.3–0.7 ng/ml, and relative standard deviation < 8.1%, respectively. Relative recoveries in spiked real samples ranged from 94.67 to 109.45% with a standard deviation < 6.05%. The proposed method is effective, sensitive, and reusable and it is promising for the analysis of polycyclic aromatic hydrocarbons residues in environmental samples.
