Advantages of online total nitrogen analyzer

Total nitrogen refers to the nitrogen content in soluble and suspended particles, including nitrite nitrogen, nitrate nitrogen, inorganic ammonium salts, dissolved ammonia, and nitrogen in most organic nitrogen-containing compounds in water. When lakes and reservoirs contain excessive nitrogen and phosphorus substances, it causes vigorous reproduction of phytoplankton and leads to eutrophication. Therefore, eutrophication caused by total nitrogen has become a major environmental issue that countries around the world attach great importance to, and total nitrogen has also become one of the important indicators for controlling water quality. The measurement method of this instrument mainly adopts alkaline potassium persulfate digestion ultraviolet spectrophotometry.

When the nitrite nitrogen in water is too high, drinking this water will combine with proteins to form nitrosamines, which are strong carcinogens and extremely harmful to the body. Moreover, under anaerobic conditions, ammonia nitrogen can also be converted into nitrite nitrogen; The nitrate nitrogen in drinking water is reduced to nitrite nitrogen by the action of nitrate reducing bacteria in the human body, and the toxicity will be 11 times that of nitrate, mainly affecting the ability of hemoglobin to carry oxygen and causing suffocation in the human body.
Total nitrogen is the main indicator reflecting eutrophication of water bodies. The occurrence of the Taihu Lake Lake water pollution event has made the regulatory authorities realize the harmfulness of total nitrogen again. Mastering the total nitrogen emissions, distribution, and main sources is of great significance for controlling eutrophication of water bodies and improving water quality.
