The objective of this research is to examine the effect of some important soil variables under controlled laboratory conditions on supercritical extraction of polychlorinated biphenyls (PCBs) from soils. Furthermore, it is also proposed to evaluate the properties of soils before and after supercritical extraction is performed. Numerous sites in this country are contaminated with PCBs. The remediation of PCB contaminated sites requires the excavation and treatment of the contaminated soil. This information this research will provide is required before treated soil can be safely returned to its original site.

本研究的目的是研究在受控的实验室条件下，一些重要的土壤变量对土壤中多氯联苯（PCBs）的超临界萃取的影响。此外，还提出了评价超临界萃取前后土壤性质的方法。这个国家的许多地方都被多氯联苯污染了。多氯联苯污染场地的修复需要对污染土壤进行挖掘和处理。在处理过的土壤能够安全返回到原址之前，这项研究将提供的这些信息是必需的。
