SOXHLET EXTRACTION OF PENTACHLOROPHENOL FROM SOIL WITH IN SITU DERIVATIZATION

The traditional Soxhlet extraction of pentachlorophenol (PCP) from soil samples has been modified to allow a rapid and efficient extraction. The modified procedure includes a derivatization in situ of the soil sample during the extraction. The traditional Soxhlet extraction (TSE) was compared with S...

Pentachlorophenol supercritical fluid derivatization Soxhlet extraction soil derivatization in situ The traditional Soxhlet extraction of pentachlorophenol (PCP) from soil samples has been modified to allow a rapid and efficient extraction. The modified procedure includes a derivatization in situ of the soil sample during the extraction.

Two different mixtures of derivative reactives, trietylamine-acetic anhydride (TEA-AA) and pyridine-acetic anhydride (PYR-AA), were utilized.
