Description
The VISOCOLOR® alpha Ammonium Test Kit is for the colorimetric determination of ammonium.
In alkaline medium ammonium ions react with chlorine to form chloramine which in the presence of catalyst forms a blue coloured indophenol with phenols.
Ammonium ions occur primarily in domestic waste waters, but frequently also in industrial waste waters. In surface and ground waters, ammonium ions indicate decomposition of animal or vegetable matter. Control of the ammonium values is therefore important to the water supply, as a contamination indicator.
Suitable for testing sea water.
