An analytical method for the determination of aromatic amines in water is introduced that uses iodination with a Sandmeyer- like reaction to replace the amino group by iodine in aqueous solution. The non-polar derivatives are extracted with pentane or toluene, separated with gas chromatography and sensitively detected with an ECD. Thirteen major metabolites of nitroaromatic explosives were investigated. The method was used to analyze these metabolites in water samples from the site of a former ammunition plant. The results are compared with the derivatization of aromatic amines via bromination of the aromatic ring.
