标准摘要
[中文适用范围]： ISO 12782 的这一部分规定了用草酸铵/草酸萃取土壤和其他材料中无定形氧化铝和氢氧化物形式的“活性”铝含量的测定。其他材料还包括废物。“活性”铝的含量可用作地球化学模型的输入。 [外文原描述]： 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.
英文名称Soil quality — Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials — Part 3: Extraction of aluminium oxides and hydroxides with ammonium oxalate/oxalic acid
