Ammonia nitrogen mainly refers to non ionized ammonia (NH)₃）And ammonium ions (NH)₄⁺）Nitrogen exists in various forms, among which non ionized ammonia is the main factor causing toxicity to aquatic organisms. Ammonia nitrogen is a nutrient in water bodies that can lead to eutrophication. Our country's environmental protection department has taken many measures to require the detection of ammonia nitrogen in industrial wastewater and domestic sewage samples from industries such as fertilizers, smelting, and synthetic detergents. The discharge standard for urban sewage treatment plants (GB 18918-2002) stipulates that the first level standard for ammonia nitrogen shall not exceed 5mg/L, and the second level standard shall not exceed 25mg/L.

Harvey Sen's production based on ammonia nitrogen water sample acid spectrophotometryAmmonia nitrogen (ultra-low) reagent water quality testingReagents have the advantages of a wide testing range, accurate results, good parallelism, strong anti-interference ability, easy operation, low cost, and no harmful substances such as heavy metals in the testing waste liquid. Suitable for the requirements of batch, rapid, and accurate determination of various water quality.
