摘要/Abstract

摘要： 提出了固相微萃取-气相色谱质谱(solid phase microextraction-gas chromatography mass spectrometry, SPME-GC/MS)检测水体中 6 种酞酸酯(phthalate esters, 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∼8.5 ng/L, 在 20∼500 ng/L 范围内线性相关系数 r²> 0.991, 加标回收率为 83%∼112%, 相对标准偏差(relative standard deviation,RSD)为 1.1%∼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.

Abstract: 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.

Key words: environmental water detection, phthalate ester (PAE), solid phase microextraction (SPME)
