Abstract:

通过静态吸附实验,研究了不同温度下,柴油在土壤中的吸附行为,探讨了阴离子表面活性剂SDS和非离子表面活性剂Tween80对柴油吸附的影响。结果表明,Langmuir吸附方程对柴油在3种土样中的吸附等温线的拟合效果较好,3种土样吸附能力的大小顺序为轻粘土>中壤土>重壤土;温度升高不利于柴油在土壤中的吸附;SDS和Tween80均利于柴油在土壤表面的解吸,且SDS的解吸效果更好。柴油的吸附量随SDS浓度的升高而降低。当Tween80的浓度小于临界胶束浓度CMC时,柴油的吸附量随Tween80浓度的升高而升高;当Tween80的浓度等于或大于CMC时,吸附量随Tween80浓度的升高而降低。
