摘  要:
选用阴离子表面活性剂十二烷基苯磺酸钠和十二烷基硫酸钠(LAS和SDS),阳离子表面活性剂十六烷基三甲基氯化铵(CTAB)和非离子表面活性剂(AEO-9和SA-20)对污染土壤进行解析试验。研究了用表面活性剂解吸土壤中的苯系物,从而为淋滤冲洗被石油污染的农田提供理论依据。试验表明,阴离子表面活性剂对苯系物的去除效率达95%,非离子表面活性剂对苯系物的去除率达85%,而阳离子表面活性剂无明显去除效果。

摘  要:
The desorption of benzene compounds from soil in surfactant solutions was investigated in the present study.Anionic surfactants(LAS and SDS),cationic surfactant (CTAB)and nonionic surfactants(AEO -9and SA -20)were utilized to desorb the contaminated soil in the experiment .The results showed that the removal rate of benzene compounds was up to 95%in anionic surfactant solution,and 85%in noni onic surfactant solution,respectively,but the removal rate was not obvious in cationic surfactant solution.
