ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of 2,4-dinitrotoluene. It presents detailed information on the analysis of aqueous and nonaqueous samples of 2,4-dinitrotoluene. 2,4-Dinitrotoluene 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-dinitrotoluene, aqueous samples are repeatedly extracted with methylene chloride. Extracts are combined and concentrated by evaporation of methylene chloride. Then, Florisil cleanup method is carried out. The extract is analyzed on gas chromatography/mass spectroscopy (GC/MS) or GC-electron capture detector (GC-ECD). Soil, sediment, or solid waste is extracted with methylene chloride by sonication or Soxhlet extraction. For Florisil cleanup, column is eluted with methylene chloride/hexane and then with acetone/methylene chloride mixture.
