Some people ask, what is nitrate nitrogen? What’s the difference between nitrite and nitrogen? How do you know if there’s too much nitrate nitrogen in the water? Don’t hurry! This chapter water quality online monitoring instrument manufacturers to understand the above problems together with you.

Nitrate nitrogen (NO3-N) is the product of oxidative decomposition of nitrogen-containing organic matter. If only the nitrate content in the water body increases, then the ammonia nitrogen (NH3-N) and nitrite nitrogen (NO2-N) contents are low or even no, indicating that the water quality has been polluted for a long time and has now tended to self-purification. Nitrates in water can also come directly from the formation. Nitrite nitrogen is the intermediate product of the further oxidation of nitrogen-containing organic matter in the water body and the process of becoming nitrate. The presence of nitrite in water indicates that the decomposition process of organic matter is still continuing, and the content of nitrite is too high, that is, the inorganic process of organic matter in water is quite strong, indicating that the risk of pollution still exists.

So How Do You know If There are too Many Nitrates in the Water?

This can be detected by water quality monitoring equipment, and the NO3N-8000 nitrate nitrogen online analyzer produced by Hangzhou Modi automatically analyzes and monitors the nitrate nitrogen content in surface water, domestic sewage and industrial wastewater. The working principle is that the water sample is injected into the reaction tank by the injection pump, and then the pH value of the solution is adjusted, and then the characteristic color developer is added, the color reaction is carried out under acidic conditions, and the colorimetric determination is carried out under a certain wavelength, and the nitrate nitrogen content in the water sample is calculated according to the Lambert-Beer law.
