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