PINPOINTING AND DETERMINATION OF PYRANINE 120 % COLORANT IN LEAK WATER
The Pyranine 120 % colourant is chemically the sodium salt of 3-oxypyrenetrisulphonic acid. It is used to colour district heating water when seaking leaks into warm domestic water supplies. It colours the water a fluorescent yellowish green, and small amounts can be detected either by UV light or spectrophotometrically. It is not detrimental to health.
