ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of 2,4,6-trichlorophenol. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of 2,4,6-trichlorophenol. 2,4,6-Trichlorophenol is crystalline solid with strong phenolic odor. It is insoluble in water and soluble in most organic solvents. During the analysis of aqueous and nonaqueous samples of 2,4,6-trichlorophenol, pH of aqueous samples is adjusted to below 2 and extracted with methylene chloride. The extract is concentrated and analyzed by gas chromatography/mass spectrometry (GC/MS) or GC-FID. Aqueous samples may be analyzed by high-performance liquid chromatography (HPLC) on an underivatized polystyrene–divinylbenzene column such as Poly-RP CO or a C-18 reverse-phase column. During the air analysis of 2,4,6-trichlorophenol, airborne particles are collected on a sorbent cartridge containing polyurethane foam. Deposited particles are extracted with 5" diethyl ether in hexane and the extract is analyzed by GC-ECD.
