| 摘 要： | 采用平衡振荡法，研究了砂土对非离子表面活性剂Triton X-100的吸附特征。结果表明，砂颗粒对Triton X-100的吸附能力总体较低，单位吸附含量均＜1.1 mg/g；砂颗粒吸附Triton X-100过程中存在显著的吸附剂浓度效应，砂颗粒上Triton X-100含量随着固液比（吸附剂浓度）的增大而减小；吸附容量qm与平衡常数KL值随固液比变化而变化，Langmuir方程适用范围是起始浓度C0相对较小的固液吸附体系；0.5～1 mm石英砂的吸附能力略＞0.2～0.5 mm石英砂，0.5～1 mm和0.2～0.5 mm石英砂吸附Triton X-100变化特征具有显著的一致性，采用高斯拟合模型可以反映出石英砂吸附Triton X-100的变化规律，相关系数R2均＞0.98。

| Abstract: | Absorbed surfactant has a significant influence on surfactant-enhanced flushing for hydrophobic organic pollution in soils.Equilibrium oscillometry was conducted to investigate the sorption characteristics of nonionic surfactant(Triton X-100) in sand soil.The results showed that the content of absorbed Triton X-100 is lower than 1.1 mg/g in different grain size sand soil.The effect of absorbent concentration is obviously for Triton X-100 sorption,and Triton X-100 content decreases with the increasing of sol... |
