| 摘 要： | 研究了用表面活性剂去除黄土中柴油类污染物。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)和阳离子表面活性剂十六烷基三甲基溴化铵 (CTAB)对污染的土壤进行解吸实验 ,表明阴离子表面活性剂浓度从 0 .1%增加到 1.0 %时 ,其柴油的去除率可达 2 0 % ,而阳离子表面活性剂去除作用不甚明显。利用摩尔增溶比MSR值求得LAS和SDS的logKm 值为 4.5 5 2和 3 .63 0 ,这和理论的计算值很接近

| Abstract: | The removal of diesel contaminant from loess soil by using surfactant solutions was investigated. The anionic surfactants (LAS and SDS) and cationic surfactant (CTAB) were utilized to desorb the contaminated loess soil in the laboratory. The removal rate of diesel was up to 20% at a range of anionic surfactant concentrations from 0.1% to 1%, but the removal rate with the cationic surfactant appeared insignificant. The logK m values of LAS and SDS were calculated as 4.552 and 3.630 respectively based on the value of molar solubility ratio (MSR), which was almost identical to the theoretical value. |
