DNAPL인 TCE, PCE의 특성은? | 토양 및 지하수의 오염원으로는 종류별, 양태별 등으로 수없이 많으나, 그 중 DNAPL인 TCE, PCE는 비교적 낮은 물에 대한 용해도를 가지고 있으며, 토양에 대한 낮은 흡착성을 갖고 있다. 더욱이 일반적으로 염소계 화합물들은 생물학적 처리방법에 의해 다른 독성 물질로의 변형을 통한 2차 오염원을 발생할 수 있으며, 또한 오염된 지하수 및 토양 복원에 있어 긴 처리시간이 소요되는 단점을 갖고 있다. | |
AOPs란 무엇인가? | Advanced oxidation processes(AOPs)는 강력한 산화제인 hydroxyl radical(${\cdot}OH$)를 생성하여 오염물질을 산화시키는 기법이다. 본 연구에서는 DNAPL인 trichloroethylene(TCE)과 tetrachloroethylene(PCE)의 수리학적 특성을 고려하여 우수한 고도산화처리기법($UV/Fe^{3+}$-chelating agent/$H_2O_2$기법, $UV/H_2O_2$기법)의 적용성 평가를 실시하였다. | |
TCE 분해실험에 사용되어진 PCE 오염용액은 100 mL volumetric flask를 사용하여 무엇을 제조하였는가? | water로 200 mg/L로 희석하여 제조하였다. PCE 오염용액은 100 mL volumetric flask를 사용하여 10,000 mg/L acetone stock solution을 제조한 후 D.I. |
