废输液瓶在水中卤代烃检测中的应用

Improvement of Replacing the Headspace Bottle with Waste Infusion Bottle in the Detection of Halogenated Hydrocarbon in Water

在对水中三氯甲烷、四氯化碳气相色谱检测中,用废输液瓶代替顶空瓶进行改进。本文从密封严密性、加标回收率进行试验,最终得出可以代替的结论,同时给出实验中的注意事项,以期为检测水中卤代烃提供参考。

In the determination of trichloromethane and carbon tetrachloride gas chromatography in water,the waste infusion bottle was used to replace the headspace bottle. In this paper, from the tightness of the seal, the recovery rate of the added standard was tested, and the conclusion that can be replaced was finally obtained. At the same time, the matters of attention in the experiment were given, so as to provide reference for detecting halogenated hydrocarbons in water.
