摘要
目的建立生活饮用水及水源水中灭草松、莠去津、2,4-滴、呋喃丹、五氯酚、微囊藻毒素-LR、微囊藻毒素-RR残留量的检测的超高效液相色谱-串联质谱(UPLC-MS/MS)分析方法。方法水样经微孔滤膜过滤后直接进样,采用超高效液相色谱-串联质谱电喷雾电离(ESI),多反应监测(MRM)模式检测7种有机污染物。结果灭草松、莠去津、呋喃丹、微囊藻毒素-LR、微囊藻毒素-RR在0.5~10μg/L范围内;2,4-滴、五氯酚在5~100μg/L范围内,均呈良好的线性关系,加标回收率在85.3%~103.9%,所测定的相对标准偏差在1.98%~4.78%之间。结论此方法灵敏快速,结果准确可靠,适用于生活饮用水及水源水中7种有机污染物残留检测。
Objective To establish a ultra performance liquid chromatography -mass/mass spectrometry method for the simultaneous determination of bentazone, atrazine ,2,4 - D, carbofuran, pentachlorophenol , mieroeystin - LR and microcys- tin - RR in drinking water and source water. Methods The water sample was cleaned by millipore filtration ; detected by ultra performance liquid chromatography -mass/mass spectrometry . Identification was achieved by a mass spectrometer coupled with ESI and MRM mode. Results The linear rangers for bentazone, atrazine, carbofuran, microcystin - LR and mi- crocystin - RR was good in the range of 0. 5 - 10 μg/L and the linear rangers for 2,4 - D and pentachlorophenol was good in the range of 5 - 100 μg/L. The recovery of the method was 85.3% - 103.9% and relative standard deviation （RSD）was 1.98% -4. 78%. Conclusion The method is accurate, quick, reliable for the determination of seven organic contaminants residue in drinking water and source water.
