Abstract

Spilling pollutants and its contamination to the ground have serious impact to public resulting in various research about remediation techniques. In this study, the use of amphiphilic block copolymer for remediation was investigated with a series of laboratory tests on removal of hydrophobic contaminant in soil. Four types of amphiphilic block copolymer were developed and the efficiency of the cleaning was compared with surfactant using arbitrary diesel-contaminated soils. The results of the study show that the use of amphiphilic polymer in the soil washing process significantly enhanced the remediation of the contaminated soil and a potential of new methodology of eco-friendly remediation.

지반오염에 대한 사례가 점점 증가하고 이에 따른 대책공법에 대한 연구가 꾸준히 진행되고 있다. 본 연구에서는 소수성 오염원으로 오염된 토양의 정화를 위해 친환경 양친성 블록공중합체의 개발 및 적용에 관하여 평가하였다. 오염원으로는 디이젤을 사용하였으며, 임의로 오염시킨 흙에 네 종류의 양친성 블록공중합체를 개발 및 적용하여 정화능력을 실내실험을 통하여 평가하였다. 오염된 토양을 기존 계면활성제를 사용하여 정화하고 개발된 양친성 블록공중합체의 정화능력과 비교 분석하였다. 연구결과 개발된 고분자 재료의 종류에 따라 다양한 정화능력을 보였으며, 기존 계면활성제와 비슷한 정화도를 나타내 이를 활용한 새로운 친환경적 정화재제 개발의 기초를 확립하였다.
