| A new method for transportable gas chromatography and mass spectrometry (GC/MS) with solid phase micro-extraction (SPME) technology was established in order to analyze semi volatile organic compounds in water. Several parameters was studied and optimized: such as SPME fiber, extraction temperature, extraction time, ion intensity, thermal desorption temperature and time, stirring rate and so on. Under optimal conditions, the method possesses good linear range (1.00 μg/L～40.0 μg/L), low detection limit (0.11 μg/L～0.39 μg/L), good analytic precision (RSD≤14.3%) and excellent accuracy (the average recoveries were between 51.0% and 98.5%). The method was able to qualitatively and quantitatively analyze 24 kinds of SVOCs, 7 kinds of OPPs, 17 kinds of OCPs in water quickly and effectively. It is suitable for environment emergency monitoring for analysis of SVOCs in water. |
