Iron (Low Reading)
The Palintest Iron LR test is based on a single tablet reagent containing 3-(2-Pyridyl)-5, 6-bis(4-phenyl-sulphonic acid)-1,
2, 4-triazine (PPST) formulated with a decomplexing/reducing agent in an Acid buffer.
The test is simply carried out by adding a tablet to a sample of the water under test.
The decomplexing/reducing agent breaks down weakly complexed forms of iron, and converts the iron from the ferric to the ferrous form.
The ferrous Iron reacts with PPST to form a pink coloration.
The intensity of the colour produced is proportional to the Iron concentration and is measured using a Palintest Photometer.
