摘　　要：采用固相萃取-氢火焰离子化检测器气相色谱法测定水中15种酞酸酯类化合物,通过试验优化前处理条件,使方法在0.500 mg/L^20.0 mg/L范围内线性良好,方法检出限为0.20μg/L^0.39μg/L。空白水样的加标回收率为66.6%~120%,试验6次结果的RSD为5.7%~12.5%。用该方法测定实际水样,加标回收率为66.8%~119%,6次测定结果的RSD为5.4%~11.8%。Fifteen kinds of PAEs in water were determined by gas chromatography with solid-phase extraction in this research. The optimal conditions of pretreatment were discussed. The results indicated that the linearity was good from 0. 500 mg/L to 20. 0 mg/L. The detection limits were from 0. 20 μg/L to 0. 39 μg/L. The spiked recoveries of blank water samples were 66. 6% ~ 120%,and the relative standard deviations of 6 repeated measurements were 5. 7% ~ 12. 5%. The spiked recoveries of actual water samples were 66. 8% ~ 119%,and the relative standard deviations were 5. 4% ~ 11. 8%.
