Description
The NANOCOLOR® Ammonium Tube Test Kit is for the photometric determination of ammonium.
At a pH value of about 12.6 ammonium ions react with hypochlorite and salicylate in the presence of sodium nitroprussiate as catalyst to form a blue indophenol. Good reproducibility is obtained for weakly polluted waters. Heavy pollution causes errors, unless a distillation precedes the analysis. Strongly acidic and buffered samples have to be adjusted to pH 9 – 10 for the test using sodium hydroxide solution.
Compatible with the following photometers:
