2020 ammonia nitrogen water quality online analyzer-j9九游会官方

application areas

the 2020 ammonia nitrogen water quality online analyzer is designed for online monitoring of ammonia nitrogen content in various water sources, including surface water, groundwater, water supply sources, municipal water supply, industrial wastewater, and municipal sewage.

detection principles

salicylic acid spectrophotometry: in the presence of an alkaline medium and a catalyst, ammonia and ammonium ions in water react with salicylate to form a colored compound. the absorbance of this substance is proportional to the ammonia nitrogen content. the absorbance is measured at a specific wavelength.

nessler's reagent spectrophotometry: ammonia nitrogen, existing in the form of free ammonia or ammonium ions, reacts with nessler's reagent to produce a colored compound. the absorbance of this substance is proportional to the ammonia nitrogen content. the absorbance is measured at a specific wavelength.
