Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of crystalline iron oxides and hydroxides with dithionite Ingestion-build-730731 Scope This part of ISO 12782 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. NOTE Although the ammonium oxalate oxalic acid extraction (ISO 127823) is commonly
