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.
