Application

Ammonium iron(II) sulfate hexahydrate has been used in a study to assess the catalytic effect of different forms of iron in purification of single-walled carbon nanotubes. Ammonium iron(II) sulfate hexahydrate has also been used in a study to determine trace amounts of Se(IV) in seawater.
In culture media for the detection of sulfate-reducing bacteria;
