气相色谱-质谱法测定HC型发烟剂浸取回收工艺废水中的六氯乙烷

Gas Chromatography-Mass Spectrometry Determination of Hexachloroethane in Wastewater from the Extraction and Recovery Process of HC-type Smoke Agents

建立了HC型发烟剂浸取回收工艺废水中挥发性有机物六氯乙烷的气相色谱-质谱法分析方法。结果表明,该方法对六氯乙烷的检出限为10.6μg/L,空白加标回收率为99.93%~105.70%,相对标准偏差(n=6)为0.73%~2.60%。该方法操作简便,准确度和灵敏度高,适用于HC型发烟剂浸取回收工艺废水中六氯乙烷的污染监测。

A gas chromatography-mass spectrometry method for the determination of was developed for the determination of volatile organic compound hexachloroethane in wastewater from the extraction and recovery process of HC-type smoke agents.The results showed that the detection limit of hexachloroethane was 10.6μg/L,the recovery rate of blank spiking was 99.93%~105.70%,and the relative standard deviations(n=6)were 0.73%~2.60%.As a simple,accurate and sensitive method,it is suitable for the pollution monitoring of hexachloroethane in wastewater from the extraction and recovery process of HC-type smoke agents.
