英文摘要	表面活性剂具有增溶和乳化性质,能够有效去除土壤中的石油类污染物。本研究以实验室配制的原油污染土壤和苯并[a]蒽污染土壤为供试土壤,采用批量洗脱方法,研究阴、阳离子和非离子等11种表面活性剂的洗脱效果,从而筛选出效果较好的单一表面活性剂进行阴–非复配,并以苯并[a]蒽污染土壤为试验土样,采用单一控制变量法研究复配比、浓度、液固比、温度和添加无机盐种类对洗脱效果的影响。结果表明:对单一表面活性剂,洗脱效果最好的为SDS、Tw80和TX100,三者在浓度10 g/L,液固比为40︰1时对苯并[a]蒽去除率分别为85.3%、74.3%和67.9%;在浓度6 g/L,液固比为20︰1时对原油的去除率分别...
中文摘要	Surfactants have the potential to clean up the crude oil contaminated soil owing to their excellent properties of solubilization and emulsification. Here, the elution efficiency of crude oil and Benz[a]anthracene from soil by 11 kinds of surfactants including anionic, cationic, and non-ionic surfactants were examined using batch elution experiments. According to the elution efficiency, better anionic and nonionic surfactants were selected and mixed, and then, the influence of mass ratio, concentration of mixed surfactants, liquid soil ratio (L/S), temperature and the species of the added inorganic salts on elution efficiency of Benz[a]anthracene in contaminated soil were investigated in the experiment. The results showed that, for single surfactant, SDS, Tw80 and TX100 had greater effects on Benz[a]anthracene and crude oil elution test, and the elution rates of Benz[a]anthracene were 85.3%, 74.3% and 67.9% under the condition of concentration of 10 g/L and liquid soil ratio of 40︰1, meanwhile, the elution rates of crude oil were 65.3%, 57.6% and 67.3% under the concentration of 6 g/L and liquid soil ratio of 20︰1, respectively. The solubilization of Benz[a]anthracene could be increased significantly by SDS-Tw80 mixed surfactants. The elution rate of Benz[a]anthracene could be up to 84.5% when the concentration and the mass ratio of SDS-Tw80 were 6 g/L and 6︰4, the liquid soil ratio (L/S) was 20︰1, the concentration of sodium carbonate as additive was 0.02 mol/L.
