ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of tetraethyl pyrophosphate. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of tetraethyl pyrophosphate. Tetraethyl pyrophosphate is an organophosphorus pesticide, colorless liquid, miscible with most organic solvents, and highly toxic. During the analysis of aqueous and nonaqueous samples of tetraethyl pyrophosphate, aqueous samples are extracted serially with methylene chloride. The extract is concentrated and analyzed by gas chromatography/mass spectrometry (GC/MS). Soil, sediment, or solid waste sample is mixed with anhydrous Na2SO4. During the air analysis of tetraethyl pyrophosphate, air is drawn through a solid sorbent tube containing Chromosorb 102.
