디젤오염 철도토양의 토양세정법 적용을 위한 계면활성제 선정 연구

초록

Generally, the clean-up of oil-contaminated soil has been substantially conducted in the field. The soil pollution of railroad site has been caused by oil leakage at fueling or around UST. Therefore, in-situ soil flushing was performed using nonionic surfactant for diesel-contaminated railroad soil in this study. The basic properties of field soil were investigated and six kinds of nonionic-surfactants were tested including Tergitol 15-S-9, Tergitol NP10, Tween 85, Triton X-100, Brij 56 and Brij 76. As a result, Triton X-100 and Tergitol 15-S-9 showed the highest TPH removal efficiency. In conclusion, these results can be applied to remove diesel from contaminated railroad field using soil flushing.
