Abstract

Contamination of the unsaturated zone, and hence, of groundwater by non-aqueous phase liquids has become a problem that arouses great concern due to the environmental damage it causes. Several efficient and economically beneficial techniques for the in situ treatment of contaminated soils have been applied quite frequently, including the so-called soil flushing processes. In this study, microemulsion systems were prepared using limonene, in the search for a formulation that would remove trichloroethene in soil. Limonene, a monocyclic monoterpene, is one of the main constituents of various essential oils of citrus fruits, such as oranges, tangerines and lemons. The results indicated that using a washing fluid containing 15 % DL-limonene microemulsion enabled the removal of 98.85 % of trichloroethene present in the soil after 30 minutes of residence time in the system. Hence, it can be concluded that the use of this microemulsion system is an inter-esting strategy for the remediation of soils contaminated with trichloroethene.
DL-柠檬烯微乳体系修复不饱和区有机氯化合物
非水相液体对非饱和带的污染,以及地下水的污染,由于其对环境的破坏,已成为一个引起极大关注的问题。现场处理受污染土壤的几种有效和经济上有益的技术已被广泛应用,包括所谓的土壤冲洗过程。在本研究中,用柠檬烯制备了微乳体系,以寻找一种能去除土壤中三氯乙烯的配方。柠檬烯是一种单环单萜,是柑橘类水果(如橙子、橘子和柠檬)的各种精油的主要成分之一。结果表明,使用含有15%DL-柠檬烯微乳液的洗涤液,在系统中停留30分钟后,能够去除土壤中98.85%的三氯乙烯。因此,可以得出结论,使用该微乳液系统是一种修复三氯乙烯污染土壤的试验策略。
