Abstract

In this stduy, the column experiments were carried out assuming the soil was contaminated by leakage of gasoline containing MTBE from USTs and pipes around gas stations. Then, characteristics of MTBE transport in the soil were investigated using CXTFIT program. The column experiments with different soil properties, moisture content, organic matter content and flow rate were carried out. Some parameters(D, R, $\beta$, $\omega$) used in two-site non-equilibrium adsorption model were obtained from measuring the MTBE concentration in injection-liquid and in effluent and using CXTFIT program. In addition, The characteristics of MTBE transport in the soil was found using BTCs and obtained parameters. Consequently, the advection decreased as the increase of the content of fine particle and organic, while the MTBE transport by advection was enhanced as increasing flow rate and moisture content.

본 연구에서는 주유소 등의 지하 유류저장탱크나 파이프의 제한된 수명으로 인해 발생할 수 있는 가솔린의 누출에 의해 MTBE로 토양이 오염되었을 경우를 가정하여, 칼럼실험을 수행하고, CXTFIT 기법을 이용하여 토양 내 MTBE의 이동특성을 살펴 보았다. 칼럼실험에서는 토성, 수분함량, 유기물함량, 주입유속을 달리하여, 주입액과 유출액의 MTBE의 농도 측정값을 비교하고, CXTFIT기법을 이용하여 two-site 비평형 흡착모델에 사용된 매개변수(D, R, $\beta$, $\omega$)를 구하였다. 이들 매개변수와 파과곡선을 이용하여 MTBE의 토양 내 이동특성을 살펴보았다. 토양 내 미세입자와 유기물함량이 많을수록 이류에 의한 영향이 감소하는 것으로 나타났으며, 수분함량과 유속의 증가는 이류에 의한 MTBE의 이동을 더욱 가속시키는 것으로 나타났다.
