ABSTRACT

This chapter briefly discusses the application, chemical properties and physical properties of pentachlorophenol. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of pentachlorophenol. Pentachlorophenol is a crystalline solid, which is insoluble in water and soluble in organic solvents. During the analysis of aqueous and nonaqueous samples of pentachlorophenol, pH of nonaqueous samples is adjusted to below 2. Aqueous samples are extracted with methylene chloride. The extract is concentrated and analyzed by gas chromatography/mass spectrometry (GC/MS) or gas chromatography-flame ionization detector (GC-FID). Alternatively, extract is exchanged into 2-propanol and derivatized with pentafluorobenzyl bromide. Aqueous samples may be analyzed by high-performance liquid chromatography (HPLC) using a C-18 derivatized reverse phase column or on an underivatized polystyrene-divinylbenzene column such as Poly-RP CO.
