ISO 12782-2:2012 specifies the determination of the content of "reactive" iron in the form of crystralline iron oxides and hydroxides in soil and other materials by extraction with dithionite. Other materials also include waste. The content of "reactive" iron can be used as input in geochemical models to represent the content of crystalline iron (hydr)oxides.
