Abstract

Liquid/liquid and solid/liquid extraction methods for the determination of explosives and related compounds in aqueous samples of former ammunition production sites were tested and validated. For the instrumental analysis of these pollutants mainly methods based on gas chromatography (GC) and high performance liquid chromatography (HPLC) were developed and validated, where the former method is suited for thermally stable, the latter for thermally labile explosives. Apart from methods for the analysis of nitroaromatics, nitramines and nitrate esters also methods for the determination of nitrophenols, chlorinated nitrobenzenes and aromatic amines were developed. These compounds are by-products for degradation products in ammunition waste. Moreover, the method of 'automated multiple development' thin layer chromatography and the proton nuclear magnetic resonance have been applied to the identification and quantitation of explosives and related compounds. The AMD technique is particularly suited for a rapid screening of a large number of aqueous or solid samples. The NMR technique allows the 'non-target'-analysis of compounds in aqueous samples of ammunition hazardous waste sites. Using this method a variety of hitherto unknown pollutants could be identified.
