Simultaneous Determination of 14 Semi-volatile Organic Pollutants in Water by Direct Injection Ultra-high Performance Liquid Chromatography Tandem Mass Spectrometry
A method of direct injection ultra high performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS)has been es-tablished 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(R2≥0.99)between 0.5-100 μg/L;the limit of detection was 0.011-0.042 μg/L,the limit of lower determination was 0.046-0.169 μg/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.
