采用顶空气相色谱法分离 ECD 检测器定量法(HS/GC-ECD) 快速测定土壤中 14 种挥发性卤代烃.实验证明,14 种挥发性卤代烃在气相色谱条件下实现很好的基线分离, 方法的检出限为 0. 004 ~ 1. 202 ug/kg, 测定下限为 0. 02 ~ 4. 81 ug/kg.加标低、 中、 高三种不同浓度的标准物质,得出土壤中 14 种挥发性卤代烃的相对标准偏差(RSD) 分别为 1. 1%~ 9. 1% 、 5. 5% ~ 10. 5% 和 3. 2% ~ 13. 8,加标回收率分别为 85. 3% ~ 106. 4% 、 88. 2% ~ 106. 0% 和 91. 4% ~ 114. 1%.
The method of determining the 14 kinds of volatile halogenated hydrocarbons in soil by using headspace gas chromatography-ECD spectrometry (HS/GC-ECD) was used in this article. Experimental results showed that the 14 kinds of volatile halogenated hydrocarbons had good baseline separation under gas chromatography parameters. The detection limit of this method were 0. 004 ~ 1. 202 ug/kg, and the determination limit of this method were 0. 02 ~ 4. 81 ug/kg. The relative standard deviations were 1. 1% ~ 9. 1% 、 5. 5% ~ 10. 5% and 3. 2% ~ 13. 8, the recovery rates were 85. 3% ~ 106. 4% 、 88. 2% ~ 106. 0% and 91. 4% ~ 114. 1% when adding low, medium, and high concentrations of standard substances of the 14 kinds of volatile halogenated hydrocarbons in soil,sample.
