| 中文摘要 |
| 探讨了表面活性剂清洗法对土壤中芳烃类污染物的清除作用，并对常州市染化厂原址污染现场土壤样品进行了清洗研究．研究表明，表面活性剂对土壤中的芳烃类污染物有很好的去除效果，十二烷基苯磺酸钠溶液对土壤中苯酚、硝基苯洗脱率分别达９３．９７％ 和７８．７４％ ．对污染现场土壤样品中主要污染物的洗脱率达９０％ 以上 |
| 英文摘要 |
| The effect of surfactants in removing aromatic contaminants from soil was investigated. The results showed that aromatic contaminants can be removed effectively from soil by elution with surfactants. The elution efficiency of phenol and nitrobenzene from soil by sodium laurylbenzosulfonate were 93 97% and 78 74% respectively. The elution efficiency for the main contaminants in situ soil sample was higher than 90%. |
