Abstract: Ammonia nitrogen is an important monitoring index of water environment. Nessler reagent spectrophotometry is the
main method of environmental monitoring. This paper summarized the main influencing factors, interference substances and elimination
methods of this method, so as to optimize the method and reduce the error, so as to make the data more accurate and reliable.
Key words: ammonia nitrogen; Nessler reagent spectrophotometry; influencing factor
