Soil quality — Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials — Part 2: Extraction of crystalline iron oxides and hydroxides with dithionite 土壤质量——土壤和材料中成分浸出和形态形成的地球化学模拟参数第2部分:用连二亚硫酸钠萃取结晶氧化铁和氢氧化物

发布日期： 2012-06-01

ISO 12782-2:2012规定了用连二亚硫酸钠萃取法测定土壤和其他材料中以结晶铁氧化物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，以表示结晶铁（hydr）氧化物的含量。

ISO 12782-2:2012 specifies the determination of the content of "reactive" iron in the form of crystralline iron oxides and hydroxides in soil and other materials by extraction with dithionite. Other materials also include waste. The content of "reactive" iron can be used as input in geochemical models to represent the content of crystalline iron (hydr)oxides.
