摘要
目的建立苯基缩水甘油醚(PGE)的溶剂解吸-气相色谱测定法。方法于2020年10至12月, 用溶剂解吸型活性炭管采集工作场所空气中PGE, 25%丙酮-二硫化碳解吸后, 经气相色谱柱分离, 氢火焰离子化检测器检测, 以峰面积定量。结果 PGE的定量测定范围为10.0~1109.0 μg/ml, 线性方程为:y=1.156x-4.328, 相关系数为0.999 7;方法检出限为3.0 μg/ml, 定量下限为10.0 μg/ml;批内和批间精密度分别为4.9%~6.4%和6.2%~6.9%;方法的加标回收率为97.2%~98.8%, 平均解吸效率为90.1%, 平均采样效率为100%, 样品在4℃内可保存7 d。结论本方法准确度高, 精密度好, 适用于工作场所空气中PGE的现场检测。
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 10.0-1109.0μg/ml,the linear equation was y=1.156x-4.328,with a correlation coefficient of 0.9997.The limit of detection was 3.0μg/ml.The lower limit of quantification was 10.0μg/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.
