Iron Test Paper (#90726)

This test paper is used for the rapid detection of iron ions (Fe²⁺ and Fe³⁺). These ions form brownish-red spots on a yellowish-white background. Mn, Mo, Ti and vanadium, if present as the cation, interfere. Interferences caused by Mn, Mo and Ti can be circumvented, however, not the interference caused by V. After prolonged storage the sensitivity may decrease. In this case wait 1 û 5 seconds for evaluation. Limit of sensitivity: 10 mg/l Fe²⁺ or Fe³⁺Note: For specific detection of iron(II) (Fe²⁺) we recommend our dipyridyl paper.
