ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of 2,4-dichlorophenol. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of 2,4-dichlorophenol. 2,4-dichlorophenol is a crystalline solid, which is insoluble in water and soluble in organic solvents. During the analysis of aqueous and nonaqueous samples of 2,4-dichlorophenol, the pH of aqueous samples is adjusted below 2. Aqueous samples are extracted with methylene chloride and the extract is concentrated and analyzed by gas chromatography/mass spectrometry (GC/MS) or GC-flame ionization detector (GC-FID). Alternatively, the extract is exchanged into 2-propanol, derivatized with pentafluorobenzyl bromide, and determined by GC-electron capture detector (GC-ECD). During the air analysis of 2,4-dichlorophenol, airborne particles are collected on a sorbent cartridge containing polyurethane foam.
