Abstract:
Objective:To establish a method for the determination of diethyl phthalate by gas chromatography in the air of workplaces.
Methods:Diethyl phthalate in the air of workplace was collected throμgh glass fiber filter, eluted with methylbenzene, and detected by gas chromatography coupled with FID detectors.
Results:The linear range of diethyl phthalate determined by this method was 14.0~1 400 μg/ml, y=2.09801x-3.66229, and the coefficient correlation was 0.999 99. The detection limit was 1.10 μg/ml, and the minimum detection concentration was 0.18mg/m3 (collected sample volume was 30 L) . The within-run precisions were 1.04%~2.75%, and the between-run precisions were 0.34%~1.30%. The recovery rates were 98.72%~103.21%, and sampling efficiency was 97.2%~100.0%. The elution efficiencies were 97.25%~98.68%. The samples could be stored at room temperature for 15 days.
Conclusion:The indicators established in this study were conformed with the requirements of GBZ/T210.4-2008, "The Guidelines for the Development of Occupational Hygiene Standards Methods Part 4: Determination of Chemical Substances in the Air of Workplaces" . Diethyl phthalate in the workplace air could be rapidly collected, accurate separated and determinated. This method is applicable to the determination of diethyl phthalate in the workplace air.
