VISOCOLOR® ECO Ammonium 15
Colorimetric determination of ammonium
Monochloramine is derived from ammonium ions as a result of the effect of chlorine in the alkaline range. Combined with thymol, this forms a blue indophenol dye. (Reaction principle analogous to APHA 4500-NH3, ISO 7150-1 & DIN 38406)

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 substances. Control of the ammonium values is therefore important to the water supply.
