Soil quality — Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials — Part 3: Extraction of aluminium oxides and hydroxides with ammonium oxalate/oxalic acid

Qualité du sol — Paramètres pour la modélisation géochimique de la lixiviation et de la spéciation des constituants des sols et des matériaux — Partie 3: Extraction des oxydes et hydroxydes d'aluminium à l'acide oxalique et à l'oxalate d'ammonium

Abstract / scope

ISO 12782-3:2012 specifies the determination of the content of "reactive" aluminium in the form of amorphous aluminium oxides and hydroxides in soil and other materials by extraction with ammonium oxalate/oxalic acid. Other materials also include waste. The content of "reactive" aluminium can be used as input in geochemical models.
