摘要：

The simultaneous determination by capillary ion electrophoresis of nitrate and nitrite in wastewaters with chloride concentrations of 15 to 23 g/l is described. Chloride concentrations over 200 mg/l hampered the determination; thus, lead, mercuric and silver acetate were used to precipitate chloride. Silver acetate added in 1.5 times the stoichiometric amount for ASCI formation gave the best results in terms of nitrate and nitrite peak resolution.
