N2 - The effects of HCl, Fe, Na and K in the determination of nitrogen as NH4+ have been studied by the method of ion chromatography. The analyzed value of nitrogen was reduced in the presence of HCl (> 9 × 10-5 mol) and K (≥2 μg) in the injected solution, while it was hardly affected by 120 μg of Fe or 30 μg of Na. In the analysis of ultra-low content of nitrogen in steel or slag, 1 mass ppm of nitrogen in the sample was determined with a CV-value = 3.5% by a combination of the steam-distillation method and ion chromatography.
