高浓度硝基苯污染土壤的淋洗试验

Leaching experiments of soil polluted by high concentration nitrobenzene

本文探讨了3种常用表面活性剂Triton X-100、Tween-80、SDBS对高浓度硝基苯污染土壤的修复洗脱作用以及土壤对3种表面活性剂的吸附作用。淋洗实验结果表明,3种表面活性剂对土壤中硝基苯的去除与蒸馏水相比没有明显去除效果,而且实验土壤对3种表面活性剂均有较强的吸附作用。这种吸附作用对土壤中硝基苯的去除有严重不利影响。

This paper has provided an investigation with the effect of the three surfactants Triton X-100, Tween - 80, SDBS on the remediation of the soil polluted by high concentration nitrobenzene. The authors have also studied the effect of soil adsorption of the three surfactants. The leaching experiments indicate that the elution eficiency of nitrobenzene from the soil by the above surfactants are not greater than distilled water. At the same time, the soil proves to absorb the surfactants stronger, thus leading to serious disadvantages in removing the nitrobenzene in it.
