摘要:
建立了顶空固相微萃取-气相色谱-串联质谱法(HS-SPME-GC-MS-MS)测定水中2,4,6-三氯酚的方法。优化条件下,在1.00~50.0μg/L质量浓度范围内线性响应良好(r2=0.999 1);检出限0.224 μg/L,测定下限0.896 μg/L;加标样相对标准偏差(RSD)为4.15%~6.24%;加标回收率为81.0%~115%;单个样品检测总时间<40 min。该方法萃取与气相色谱-串联质谱分析在线一步完成,操作简便、灵敏度高、抗干扰性强,适用于地表水、生活饮用水、工业废水等水体中2,4,6-三氯酚的检测。

Abstract:
The determination method of 2,4,6 trichlorophenol in water was established by headspace solid phase micro extraction coupled with gas chromatography tandem mass spectrometry (HS-SPME-GC-MS-MS). After the conditions were optimized, the linear relationship was good enough (r2=0.999 1) from 1.0 to 50.0 μg/L. The method detection limit was 0.224 μg/L and the method quantification limit was 0.896 μg/L. The RSDs of the spiked water were 4.15%~6.24%, and the recovery rates were 81.0%~115%. The total detection time of each sample is less than 40 minutes. The extraction and GC-MS-MS analysis of the proposed method are done online in one step. The method is easily operational, highly sensitive and strong anti interference. The method is suitable for the determination of 2,4,6 trichlorophenol in surface water, drinking water, industrial wastewater and so on.
