WS1503 Continuous Nitrogen Water Quality Monitoring Equipment Online Automatic Monitor
Product Introduction
In the presence of alkaline medium and sodium nitrite ferrocyanide (sodium nitroprusside), ammonium reacts with salicylate and hypochlorite ions to form a water-soluble blue compound with maximum absorption at 697 nm, and the amount of ammonia nitrogen in the water sample is measured by photoelectric colorimetry according to the Lambert-Bier law. A specific masking agent was added to remove the interference of cations (especially calcium and magnesium ions).
