Cyanuric Acid

Cyanuric Acid

Cyanuric acid (CYA) is best known as a stabilizing reagent for chlorine. It is widely applied in swimming pool and spa treatment programs to slow down the decomposition of hypochlorous acid. In outside pool areas, this process is accelerated by the effects of UV rays. When applied properly it can save up to 80% of normal chlorine consumption in pools during peak months. Cyanuric acid is also used in chlorinated bleaches, selective herbicides, and whitening agents. The test for cyanuric acid uses the turbidimetric method. Any cyanuric acid in the sample is precipitated out of solution and held in suspension. The amount of turbidity caused by the suspended particles is directly proportional to the amount of cyanuric acid in the sample. Hanna Instruments offers a variety of technologies to measure cyanuric acid. Spectrophotometers and benchtop photometers can measure a wide variety of other water quality parameters that are important for swimming pools and spas. Portable photometers are also available with multiple parameters.
