초록

계면활성제를 이용하여 홀입자에 흡착된 유기오염물질을 탈착시키는 실험을 실시하였다. 용매로는 중성 세제와 음이온성 세제가 사용되었으며 이를 이용하여 흙으로부터 퀴놀린 및 2-나주들을 분리하였다. 음이온성 세제로 퀴놀린은 약 80%, 2-나푸톨은 90% 가량 탈착되었으며, 중성 세제보다 음이온성 세제가 위의 두 오염물질에 대하여는 덜 효과가 좋은 것으로나타났다. 이온이 제거된 물로 두 오염물질에 대한 탈착실험을 행하여 계면활성제의 탈착능을 물과도 비교하여 보았다.

Laboratory tests were performed to desorb organic contaminants spiked onto soil particles by using surfactants. Nonionic and anionic surfactants were tested as potential desorbing solvents for extracting quinoline and 2-napthol adsorbed on soil particles. Ahionisc stirfactant remediated approximately 80% and 90% of quinoline and 2-napthol respectively and appeared to be more effective than nonionic surfactant in remediating those compounds, Comparison between simple deionized water washing of the organic contaminated soil and a given surfactant technique evaluated the improvement by the application of a Burfactant to the promotion of desorption.
