摘要: 表面活性剂胶束的存在是导致难溶有机化合物(HOCs)溶解度增加的主要原因.表面活性剂对土壤的影响很大,即使很低浓度的表面活性剂也会明显改变土壤的物理、化学和生物性质,其中表面活性剂的吸附过程起了主要作用.另外,表面活性剂的类型、结构和浓度以及所处环境条件和微生物种类都对土壤中植物、微生物生长和其本身的生物降解和去除有影响.这些都将导致土壤中原有污染物迁移转化的改变,应该引起人们的日益重视.

关键词: 表面活性剂, 增溶作用, 生物降解

Abstract: Solubility increment of hydrophobic organic compounds(HOCs) is mainly caused by the presence of surfactant micelle. Soil is exposed to a considerable quantity of surfactants, even at low concentrations, and surfactants seem to significantly alter soil physicsal,chemical and biological characteristics,with sorption process playing a dominant role. In addition, plant,soil microoganism,and bio-degradation and removal of surfactant are affected by the type, structure and concentration of surfactant, their existence circumstance,and species of microorganisms.The translocation and transformation of pollutants in soil are altered by all the above reasons, which should be paid more attention.

Key words: Surfactant, Solubilization, Biodegradation
