Abstract：Objective To establish a method for simultaneous determination of 30 kinds of semi-volatile organic compounds (SVOCs) in drinking water by gas chromatography-mass spectrometry(GC-MS). Methods SVOCs in water were extracted and concentrated by dichloromethane, then analyzed directly by GC-MS. The relative retention time of target components and mass spectrometry were used to compare the qualities. Results Under the optimum conditions, 30 kinds of SVOCs could be separated well and had a good linear relationship in a specific concentration range. The correlation coefficient was more than or equal to 0.998, and the detection limit was between 0.02 μg/l and 0.3 μg/l. The recoveries of standard addition in water samples were 79.8%-118%, and the relative standard deviation was less than or equal to 7.6%. Conclusions This method has the characteristics of high extraction efficiency, low detection cost and high accuracy and precision, and can solve the determination of 30 kinds of common SVOCs in water at one time.
