| 摘 要： | 文章介绍了持久性有机污染物的分析检测方法,指明了研究土壤中持久性有机污染物的必要性.将国内最常用的两种提取方法--索式提取和超声波提取进行比较,结果表明了索式提取的方法更适合从土壤中提取多种持久性有机污染物,提取剂和洗脱剂可选比例1:1的丙酮和石油醚,回收率可在70%～90%之间;而超声波提取的方法比较适合从土壤中提取个别的持久性有机污染物,如op′-DDT 和pp′-DDT,节省实验时间,试剂使用量少,回收率也可在50%以上.

| Abstract: | This paper mainly introduces analytical and detective technique of POPs and indicates the necessity of research on POPs in soil. By comparing Soxhlet extraction with ultrasonic method, conclusion has been obtained that Soxhlet method is suitable for extracting multiple persistent organic pollutants from oil using acetone and petroleum ether as tactant and eluant in a proportion of one to one and with a recovery rate between 70% - 90%, whereas ultrasonic method can be used for individual POPs, which needs less time and less reagent with a recovery rate of above 50%. |
