妨害物質:
Ions, e.g., antimony (III) (Sb3+), bismuth (III) (Bi3+), chloroplatinate (PtCl62–), gold (III) (Au3+), iron
(III) (Fe3+), lead (II) (Pb2+), mercury (II) (Hg2+), metavanadate (VO3–) and silver (I) (Ag+) can cause
precipitation with nitrate. Copper (Cu2+) ions can decompose the diazonium salt and cause a low
result. NCl3 can cause a red color. Strong oxidizing agents interfere.
Large quantities of color and turbidity interfere. Fats, oil, proteins, surfactants and tar interfere.
