ISO 12782-1:2012规定了用抗坏血酸萃取法测定土壤和其他材料中以无定形氧化铁和氢氧化物形式存在的“活性”铁的含量。其他材料也包括废物。“活性”铁的含量可作为地球化学模型的输入,以表示无定形铁(hydr)氧化物的含量。
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.
