槐糖脂-LAS-Na_2SiO_3复配修复石油污染土壤影响因素分析
|
摘要
选用阴离子型表面活性剂十二烷基苯磺酸钠(LAS)与内酯型槐糖脂复配,并使用硅酸钠(Na_2SiO_3)作为助剂修复石油污染土壤。使用吊片法测定单一表面活性剂以及复配药剂的临界胶束浓度,利用SPSS软件对结果进行非线性拟合。正交实验表明,LAS和内酯型槐糖脂之间存在较强的交互协同作用,三者间的复配使得洗脱率达到了87.37%。优化的复配表面活性剂的配方为:内酯型槐糖脂溶液浓度为40mg/L,硅酸钠浓度为6g/L,LAS浓度为600mg/L。析因分析结果表明,液固比对石油污染土壤的洗脱效果影响较为显著,其次是振荡时间和氧化剂浓度,各因素交互影响不明显。
Sodium dodecylbenzenesulfonate(LAS), an anion surfactant, was used to repair petroleum contaminated soil. The critical micelle concentration of single surfactant and compound agent was determined by hanging plate method. The results were fitted by SPSS software. The orthogonal experiment showed that there was a strong interaction between LAS and sophorolipids, and the elution rate reached 87.37% due to the combination of the three. The optimized formula of the compound surfactant is that the concentration of sophorolipids solution is 40 mg/L, the concentration of sodium silicate is 6 g/L and the concentration of LAS is 600 mg/L. The results of factorial analysis showed that liquid-solid ratio had a significant effect on the elution effect of oil-contaminated soil, followed by oscillating time and oxidant concentration, and the interaction of each factor was not obvious.
