Principle and Application of Ammonia Nitrogen Analyzer

Ammonia nitrogen is the nitrogen in the form of free ammonia (NH3) and ammonium ion (NH4) in water. The sources of ammonia nitrogen in water include municipal sewage, conversion of nitrite, industrial waste water such as coking synthetic ammonia and farmland drainage. Ammonia nitrogen is a nutrient in water, which can lead to eutrophication and is the main oxygen-consuming pollutant in water. It is toxic to fish and some aquatic organisms.

How Ammonia Nitrogen Analyzer works: in an alkaline medium, ammonia and ammonium ions in water react with hypochlorite to form chloramine. Under certain temperature and conditions, chloramine reacts with salicylate to form a blue-green compound, which is proportional to the concentration of ammonia-nitrogen in the water sample, thus the concentration of ammonia-nitrogen in the water sample can be calculated.

The main application scenarios include monitoring of enterprise rainwater and sewage, monitoring of ammonia nitrogen content in municipal pipe network, pumping station, ground water, river water, lake water, seawater and so on.
