标准摘要
[中文适用范围]: 本标准规定了采用七钼酸六铵(钼酸铵)测定铁矿石中磷含量的滴定法。 该方法适用于天然铁矿石、铁矿石精矿和包括烧结产品的团矿中磷浓度范围为 0.10% (m/m) 至 5.0% (m/m) 的情况。 本标准提供了滴定法测定磷的质量控制方法,但该方法不能用于裁判目的。 注:1) 该方法已在国际上对磷含量范围为 0.03% (m/m) 至 1.50%(m/m) 的样品进行了测试。 [外文原描述]: ISO 2599:2003 specifies a titrimetric method for the determination of the phosphorus content of iron ores, using hexaammonium heptamolybdate (ammonium molybdate). This method is applicable to a concentration range of 0,10 % ( m / m ) to 5,0 % ( m / m ) of phosphorus in natural iron ores, and iron ore concentrates and agglomerates including sinter products. This International Standard provides a quality control method for the determination of phosphorus by titration, however, the method cannot be used for referee purposes.
