Solubilization and behavior of surfactants in soil
表面活性剂的增溶作用及在土壤中的行为

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.
