Abstract:
Objective:To establish a solvent desorption gas chromatographymethod for the determination of phenyl glycidyl ether (PGE) .Methods:From October to December 2020, PGE in the air of workplace was collected with carbon tube and desorbed by 25% acetone-carbon disulfide. The target toxicant was separated with the gas chromatography (GC) column and analyzed with flame ionization detector (FID), and quantified by peak area.Results:The linear range of PGE in the air of workplace was 10.0-1109.0 μg/ml, the linear equation was y=1.156 x-4.328, with a correlation coefficient of 0.9997. The limit of detection was 3.0 μg/ml. The lower limit of quantification was 10.0 μg/ml. The intar-batch and inter-batch precisionswere 4.9%-6.4% and 6.2%-6.9%, respectively. The recovery rate was ranged from 97.2%-98.8%, the average collection efficiency was 100%, and the average extraction efficiency was 90.1%. The samples could be stored at 4 ℃ for 7 d. Conclusion:This method has high precision and good accuracy, and it is applicable for the determination of PGE in workplace air.
