标准摘要
[中文适用范围]: ISO 12782 的本部分规定了用抗坏血酸萃取法测定土壤和其他材料中非晶态氧化铁和氢氧化铁形式的“活性”铁的含量。其他材料还包括废物。 “活性”铁的含量可用作地球化学模型的输入,以表示非晶态氧化铁(氢)氧化物的含量。 注:尽管草酸铵/草酸萃取法(ISO 12782-3)通常用于估算氧化铁和氢氧化铁形式的“活性”铁,但 ISO 12782 的本部分与 ISO 12782-2 结合使用,已被证明分别对非晶态和结晶氧化铁(氢)氧化物的提取更为具体。 [外文原描述]: 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.
