ISO 12782-3:2012规定了用草酸铵/草酸萃取法测定土壤和其他材料中以无定形氧化铝和氢氧化物形式存在的“活性”铝含量。其他材料也包括废物。“活性”铝的含量可作为地球化学模型的输入。
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.
