Cyanuric acid is added to swimming pool water as a stabilizing agent for free<br />
chlorine residuals. It minimizes the loss of chlorine from the action of<br />
ultraviolet rays in sunlight. Cyanuric acid levels in pools should be maintained<br />
between 25 and 75 ppm and various public health associations recommend<br />
that the concentration should never exceed 100-150 ppm.<br />
APPLICATION: Swimming pool waters.<br />
RANGE: 5–200 Cyanuric Acid<br />
METHOD: A buffered solution of melamine forms a precipitate with<br />
cyanuric acid in proportion to the amount of cyanuric acid<br />
present. The amount of particles in suspension is measured<br />
SAMPLE<br />
HANDLING &<br />
PRESERVATION:<br />
turbidimetrically.<br />
Cyanuric acid samples should be analyzed as soon as possible<br />
after collection. Deterioration of the sample can be<br />
minimized by keeping samples in the dark or refrigerated<br />
until analysis can be performed.<br />
INTERFERENCES: No known interference from compounds normally found in<br />
pool water. Temperature of the sample should be maintained<br />
between 70°F and 80°F for best results. Check for stray light<br />
interference (see p. 17).<br />
