中文摘要：

提出了固相微萃取-气相色谱质谱（solidphasemicroextraction—gaschromatographymassspectrometry，SPME-GC／MS）检测水体中6种酞酸酯（phthalateesters，PAEs）的分析方法，对影响固相微萃取的萃取因素如萃取纤维、萃取时间、萃取温度、pH值进行了探讨和优化．结果显示，该方法检测限为3．7—8．5ng／L，在20—500ng／L范围内线性相关系数r^2〉0．991，加标回收率为83％-112％，相对标准偏差（relativestandarddeviation，RSD）91．1％-12．3％．该方法简单、快速，定性、定量准确可靠且灵敏度高，适用于环境水体中酞酸酯的检测．

英文摘要：

A solid phase microextraction-gas chromatography mass spectrometry （SPME-GC/MS） method was developed to determinate 6 phthalate esters （PAEs） in water. The optimum conditions, fibers, time, temperature and pH values were studied. The detection limits were 3.7-8.5 ng/L, and the correlation coefficients were more than 0.991 in linear range 20-500 ng/L. Recoveries were 83%-112% and relative standard deviations （RSDs） were 1.1%-12.3%. The SPME-GC/MS method is simple and fast, and can give high sensitivity qualitatively and quantitatively in detecting PAEs in environmental water.
