초록

본 연구에서는 사산화삼철과 활성탄을 발열체로 하여 벙커C유 오염토양에 마이크로파를 조사한 후 온도변화 양상 및 TPH 제거효율을 살펴보았다. 사산화삼철 및 활성탄 함유 오염토양에 100~500 Watt로 마이크로파를 조사하였을 때 승온율은 $1.4{\sim}1.6^{\circ}C/Watt$로 나타났다. 조사시간에 따른 온도의 변화는 활성탄보다 사산화삼철 함유토양에서 민감하게 나타났으며, 사산화삼철과 활성탄의 경우 발열체 함량이 각각 10% 이상과 25%에서 열탈착을 위한 충분한 온도가 확보될 수 있음을 관찰하였다. 사산화삼철은 평균 44.1%, 활성탄은 평균 89.4%의 TPH 제거 효율을 나타났으며, 벙커C유의 제거 양상은 활성탄이 함유되었을 때 사산화삼철 보다 고분자탄화수소의 휘발이 더욱 원활하게 진행되고 있음을 확인하였다.
