| 中文摘要:通过优选色谱柱，进一步改进色谱分离条件，优化前处理方法，建立了一种快速、高效测定水中7类27种半挥发性有机污染物（SVOCs）的GC-MS方法。该法可分析的目标物种类多、前处理速度快、萃取溶剂用量少、环境污染小、色谱运行时间短，40 min内完成分析，适用于大批量样品检测。另外，使用基质匹配标准溶液配制标准曲线，减小了基质效应，采用分段法选择离子（SIM）扫描，可获取更高灵敏度。该方法的检出限为0.000 4~0.013 μg/L，回收率为70.5%~92.8%，相对标准偏差（RSD,n=6）不大于11.2%。 |

| 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%. |
