摘要：

Electrochemical detection (ED) in the oxidative and reductive mode was applied to the analysis of nitroaromatics, nitramines, aminoaromatics and nitrophenols in groundwater samples from the surroundings of a former ammunition plant. Settings for working potential and eluent composition were optimized in terms of detection limit, linearity and selectivity. The results were compared with those obtained by UV detection and the advantages of combined UV-ED detection for the analysis of complex samples are shown.
