Soil quality — Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials — Part 1: Extraction of amorphous iron oxides and hydroxides with ascorbic acid

Qualité du sol — Paramètres pour la modélisation géochimique de la lixiviation et de la spéciation des constituants des sols et des matériaux — Partie 1: Extraction des oxydes et hydroxydes de fer amorphe à l'acide ascorbique

Abstract / scope

ISO 12782-1:2012 specifies the determination of the content of "reactive" iron in the form of amorphous iron oxides and hydroxides in soil and other materials by extraction with ascorbic acid. Other materials also include waste. The content of "reactive" iron can be used as input in geochemical models to represent the content of amorphous iron (hydr)oxides.
