Ammonia nitrogen in water refers to ammonia in the form of free ammonia, which mainly comes from the decomposition products of nitrogen-containing organic matter in domestic sewage under the action of microorganisms, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the content of ammonia nitrogen in water is high, it is toxic to fish and harmful to human beings to varying degrees. Determination of ammonia nitrogen content in water is helpful to evaluate water pollution and "self-purification", so ammonia nitrogen is an important index to characterize water pollution. Fundamental principles After the water sample is mixed with the masking agent, Ammonia nitrogen formed by free ammonia or ammonium ions reacts with salicylic acid color reagent to form a colored complex in alkaline environment and the presence of sensitizer. The analyzer detects the color change and converts this change into ammonia nitrogen value for output, and the amount of colored complex generated is equivalent to ammonia content.
