摘　　要：建立了直接进样-超高效液相色谱串联质谱法(UPLC-MS/MS)同时测定水质中乐果、涕灭威、敌敌畏、克百威等14种半挥发性有机污染物。结果表明,14种半挥发性有机污染物在0.5~100μg/L范围内线性关系较好(r^(2)≥0.99),方法检出限在0.011~0.042μg/L之间,测定下限在0.046~0.169μg/L之间;3个加标水平下的平均回收率为85.8%~118.0%,相对标准偏差为0.49%~8.31%。该方法操作简单、灵敏度高,适用于生活饮用水、地下水和地表水中14种半挥发性有机污染物的快速检测。A method of direct injection ultra high performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS)has been established for simultaneously determination of 14 semi-volatile organic pollutants including dimethoate,aldicarb,dichlorvos,carbofuran and so on in water.The calibration curves of 14 semi-volatile organic pollutants showd good linerity correlation coefficient(r^(2)≥0.99)between 0.5-100μg/L;the limit of detection was 0.011-0.042μg/L,the limit of lower determination was 0.046-0.169μg/L;the average recoveries were 85.8%-118.0%at three spiked levels,the relative standard deviation were 0.49%-8.31%.This method is simple,highly sensitive,and suitable for rapid detection of 14 semi-volatile organic pollutants in the surface,underground and drinking water.
