چکیده
|
A practical method for the elimination of pcbs from pcb-contaminated soil has been developed by the combination ofsoxhlet extraction using a newly-developed modified soxhlet extractor possessing an outlet valve on the extractionchamber with the chemical degradation. various types of pcbs contaminated in soils could be completely extracted inrefluxing hexane, and the subsequent hydrodechlorination could also be completed within 1 h in a hexane–meoh(1 : 5) solution in the presence of pd/c and et3n under ordinary hydrogen pressure and temperature without thetransfer of the extracted pcbs to other reaction container (a complete one-pot procedure). the present system is quiteuseful as a simple, safe, mild and reliable remediation method of pcb-contaminated soil.
