Abstract

In situ permeable reactive barrier (PRB) technologies have been proposed to transform or remove pollutants from contaminated subsurface environment. The majority of installed PRBs utilize zero-valent iron (ZVI) as the reactive media converting contaminants to nontoxic or immobile species. In this research, the effects of surfactant and natural organic matter (NOM) on the dechlorination of trichloroethylene (TCE) by ZVI were examined. The dechlorination rate of TCE in the presence of ZVI with surfactant and NOM was higher than that without them. This was presumed to be caused by aqueous surfactant and NOM which sorbed TCE molecules in aqueous phase and facilitated the approach of TCE to ZVI surface.

반응벽체(permeable reactive barrier, PRB) 기술은 유독성 유기화합물로 오염된 지하환경으로부터 오염물질을 제거하거나 분해시키기 위한 기술이다. 반응벽체 기술에 사용되는 반응물질로 0가 철 (zero-valent iron. ZVI) 이 가장 광범위하게 연구되어져 있는데. ZVI의 산화는 독성이 높은 염소계 유기화합물을 독성이 낮은 물질로 탈염소화시킬 수 있다. 본 연구는 ZVI에 의하여 염소계 화합물인 TCE가 탈염소화 반응이 일어날 때 지하환경에 인공적으로 혹은 자연적으로 공존할 수 있는 계면활성제와 자연용존 유기물 (natural organic matter. NOM)의 영향을 알아보는 것을 그 목표로 한다. ZVI에 의한 TCE의 탈염소화 반응속도는 계면활성제와 NOM이 있을 때 더욱 증가하였는데 이는 수중에 존재하는 계면활성제와 NOM이 TCE가 ZVI로 접근하는 것을 용이하게 하여 탈염소화 반응속도를 증가시키는 것으로 사료된다.
