| Research Abstract |
Anionic surfactants which are the most used synthetic chemicals and discharged to the environment were investigated and detected the fundamental adsorption, decomposition and transport phenomena in a soil. Sodium dodecyl sulfate moved well at high concentration and decomposed well at low concentration in the soil. It is a good washing agent for contaminated soil. Sodium dodecyl benzene sulfonate decomposition is restricted when it is adsorbed in a soil. Further research is needed for its purification in soils.
