초록

과산소산(peroxy-acid)을 산화제로 사용하여 현장 오염토양내 존재하는 다환방향족탄화수소의 산화분해 효과를 알아보기 위하여 실험실 규모의 연구를 진행하였다. 대상 토양의 토성은 19.2 %의 토양 유기물을 포함한 pH 6.8의 사양토(sandy loam)로 확인되었으며 토양 내 다환방향족탄화수소 중 벤조(a)피렌(benzo(a)pyrene)의 농도가 평균 2.23 mg/kg으로 국내 토양환경보전법의 1 지역 우려 기준치의 3배 정도 높게 나타났다. 따라서 벤조(a)피렌 오염 토양에 대하여 유기산과 과산화수소를 이용한 과산소산 산화(peroxy-acid oxidation)처리에 의한 토양내 벤조(a)피렌의 농도 저감효과를 유기산의 종류와 유기산 및 과산화수소의 농도조건별로 평가하였다. 선정된 유기산 중 프로피온산(propionic acid)의 산화 효과가 가장 큰 것으로 확인되었으며 토양 중 벤조(a)피렌의 농도를 최종적으로 1 지역 우려 기준치 이하로 저감하였다.

Laboratory-scale experiments were conducted to assess the effect of oxidative decomposition of polycyclic aromatic hydrocarbons (PAHs) in field soil using peroxy-acid. The study soil texture is sandy soil containing 19.2 % of organic matter at pH 6.8. Among polycyclic aromatic hydrocarbons (PAHs) in the study soil, the concentration of benzo(a)pyrene is 2.23 mg/kg which is three times higherthan the Korea standard level. Therefore benzo(a)pyrene was selected as the target study PAH for the treatment by peroxy-acid oxidation using peroxy-acid coupled with hydrogen peroxide, and the efficiency of the oxidative decomposition of benzo(a)pyrene was assessed for the different organic acids and dosages of an organic acid and hydrogen peroxide. Propionic acid among the tested organic acids showed the highest efficiency of benzo(a)pyrene reduction in the peroxyacid oxidation treatment and finally satisfied the Korea standard level.
