Product Overview: Total nitrogen in water mainly comes from decomposition products of nitrogen-containing organic matter in domestic sewage by microorganisms, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the total nitrogen content in water is high, it is toxic to fish and harmful to humans in varying degrees. The determination of total nitrogen in water is helpful to evaluate the pollution and self-purification of water, so total nitrogen is an important indicator of water pollution.The analyzer can work automatically and continuously for a long time without attendance according to the site settings. It is widely used in industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of site test conditions, the corresponding pretreatment system can be selected to ensure the test process is reliable,test results are accurate, and fully meet the needs of different occasions.This method is suitable for wastewater with total nitrogen in the range of 0-50mg/L. Excessive calcium and magnesium ions, residual chlorine or turbidity may interfere with the measurement.
Product Principle:
After mixing the water sample and masking agent,total nitrogen in the form of free ammonia or ammonium ion in alkaline environment and in the presence of sensitizing agent reacts with potassium persulfate reagent to form a colored complex.The analyzer detects the colour change and converts the change into ammonia nitrogen value and output it.The amount of coloured complex formed is equal to the amount of ammonia nitrogen.This method is suitable for wastewater with total nitrogen in the range of 0-50mg/L. Excessive calcium and magnesium ions, residual chlorine or turbidity may interfere with the measurement.
