Reactions and transport modeling of surfactant and anthracene in the soil flushing process

摘要: Soil flushing using surfactants is a promising alternative to the pump-and-treat method of removing hydrophobic organic compounds. The interactions and transport modeling surfactant chemicals in soil were studied by batch column experiments. Sodium dodecylsulfate (SDS), an anionic surfactant, anthracene, organic, chosen as representative chemical for process. equilibrium model was observed predict SDS breakthrough columns. Mobilization anthracene from matrices medium containing noted be rate-limiting A non-equilibrium found suitable prediction breakthrough. quasi-equilibrium isotherm between solution appeared Langmuir type.
