Sodium Hypobromite.

  Product DThe hypobromite oxidation method is a common method for detecting ammonia nitrogen in seawater or high-salinity water. By increasing the concentration of the oxidant (potassium bromate-potassium bromide oxidant stock solution) and the color developer (p-aminobenzenesulfonamide solution, dihydrochloric acid-1-naphthylene diamine solution) to 5 times the original, the upper limit of the ammonia nitrogen determination of this method has been significantly increased, from the original 0.5 mg/L to 2 mg/L. The expansion of the determination range reduces the requirements of the method on water quality and environment, making the experiment simpler and easier, and is particularly suitable for determining water samples with ammonia nitrogen concentrations higher than 0.3 mg/L.etail
