| Abstract: |
| By optimizing the chromatographic column，further improving the chromatographic separation condition and optimizing the pretreatment method，a rapid and efficient method was established for the determination of 27 kinds of semi volatile organic pollutants（SVOCs） in groundwater by GC-MS. The outstanding features of this method are the variety of analytes，rapid processing，low solvent consumption，low environmental pollution and short chromatographic run time. The method could keep stable for 40 min，and is suitable for the detection of large quantities of samples. In addition，the standard curve was prepared using the matrix matched standard solution，which lead to the matrix effect reduced，and the application of the ion（SIM） scanning could obtain a high sensitivity. The detection limits of the method are in the range of 0.000 4-0.013 μg/L,and the spiked recoveries are 70.5%-92.8% with RSD（n=6） not more than 11.2%. |
