Abstract

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.

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.
