表面活性剂-振荡法处理柴油污染陕北地区土壤的实验研究

研究表面活性剂一振荡法去除陕北地区黄土中柴油类污染物的方法。实验选用阴离子表面活性剂十二烷基苯磺酸钠（LAS）和阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）及以硅酸钠为辅助剂对土壤中柴油类污染物进行去除的实验研究。实验结果说明选用阴离子表面活性剂对受污染土壤中柴油的去除率可达19％，添加辅助剂硅酸钠后去除率可达32％。实验为治理石油污染陕北地区土壤提供了选择合适表面活性剂种类的基本思路和实验数据。

Experimental Study of the Treatment for Diesel Pollution Soil of Shaanxi Northern with Surfactant - Oscillation Method

The experimental study remove diesel pollutants from shaanxi northern loess with with surfactant - oscilla- tion method. The experiment used anionic surfactant sodium dodecyl benzene sulfonate （LAS） and the cationic surfactant eetyhrimethylammonium bromide （CTAB） and sodium silicate supplemented aids diesel class of soil contaminants removal. The experimental results indicate the removal efficiency up to 19% that the selection of anionic surfactant on diesel contaminated soil. And the add auxiliary agent sodium silicate removal of up to 32%. The experiment provides the basic ideas and experimental data choose the right kind of surfactant for the treatment of oil pollution in shaanxi northern soil.
