Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of aluminium oxides and hydroxides with ammonium oxalate/oxalic acid subscription-only Three alternative methods are described:1 Scope This part of ISO 12782 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.
