The HI-3834 Iron test kit determines the iron concentration in water by conversion of the ferrous (Fe²⁺) state. The test is fast, easy and safe. The colour cube makes it simple to obtain the iron level in water. Iron can exist as ferrous (Fe²⁺) or ferric (Fe³⁺) ions. The HI-3834 test kit determines total iron levels in water via a Colorimetric method. First all ferric ions are reduced by sodium sulphite to ferrous ions. Phenanthroline complexes with ferrous ion to form an orange coloured solution, the colour intensity of the solution determines the iron concentration.
