Overview
Ammonium nitrogen can be directly taken up by plants, or converted to nitrate nitrogen through the action of nitrifying microorganisms, and subsequently assimilated by plants or microorganisms into organic nitrogen compounds. The assay principle of this kit is as follows: In a strongly alkaline medium, ammonium nitrogen reacts with sodium hypochlorite and phenol to form a water‑soluble blue dye — indophenol blue. This product exhibits a characteristic absorption peak at 625 nm, and the absorbance is directly proportional to the ammonium nitrogen content.
