The method describes how to determine the iron content of water photometrically with a cuvette test.
Iron(II) ions form a rust-colored complex with 1,10-phenanthroline. Iron(III) ions are reduced to iron(II) ions.
The method describes how to determine the iron content of water using a phenanthroline solution.
Iron(II) ions react with 1,10-phenanthroline, forming a rust-colored complex; ferric iron is reduced to ferrous iron prior to complex formation by hydroxyl ammonium chloride. The color of the solution is visually compared to a color disk using a comparator.
This method describes how to determine the iron content of water using atomic emission spectrometry.

This method describes how to determine the iron content of boiler feed water. Iron can cause surface deposits to develop.
Boiler feed water for use in the production of beer and other foods
Fe(III) ions form a complex with sulfosalicylic acid, which is red in an acidic solution and yellow in an alkaline solution. Since Fe(II) ions are oxidized in an alkaline solution, they are detected as well. In this way, the value for total iron can be measured.
This method describes how the protein content in adjuncts is determined.
