摘要
用适量的二氯甲烷提取出废水中的微量三氯乙烯(TCE),然后对萃取液进行气相色谱分析,得出萃取液中三氯乙烯的含量,换算出废水中的三氯乙烯含量。此方法的检测下限为0.5 mg/L。
Use proper quantity dichloromethane to extract the trace amount of TCE from waste water. Next, analyze the lower extraction by GC, thus we can get the content of TCE. Then which certainly can be converted into the content of TCE in waste water. The detection limit is 0.5 mg/L.
