It was demonstrated that Cl, SO42-, NO3-, N3-, ClO3, and ClO4 ions can be simultaneously and selectively determined by capillary electrophoresis using 2,4-ionene as a capillary modifier. The effect of n-butanol additives to the buffer electrolyte on the migration times of ions was shown. The optimum buffer electrolyte contained 0.5 mM Na2CrO4, 0.05% 2,4-ionene, 10%n-butanol, and 7% methanol. It was shown that azide can be identified in wash solutions obtained at the place of lead azide explosion. The detection limit for azide was 1–3 mg/L.
