Soil quality - Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Part 2: Extraction of crystalline iron oxides and hydroxides with dithionite (ISO 12782-2:2012)
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.
Der vorliegende Teil der ISO 12782 legt die Bestimmung des Gehalts an ´´reaktivem´´ Eisen in Form von
kristallinen Eisenoxiden und Eisenhydroxiden im Boden und in anderen Materialien durch Extraktion mittels
Dithionit fest. Andere Materialien schließen ebenfalls Abfall ein. Der Gehalt an ´´reaktivem´´ Eisen kann als
Vorgabe in geochemischen Modellen verwendet werden, um den Gehalt an kristallinen Eisen(hydr)oxiden
darzustellen.
