标准范围

ISO 2597-2:2008规定了两种无汞污染的滴定法,用于测定铁矿石中的总铁含量,在氯化锡(II)和氯化钛(III)还原铁(III)后使用重铬酸钾作为滴定剂。然后用稀重铬酸钾(方法1)或高氯酸(方法2)氧化过量的还原剂。这两种方法都适用于天然铁矿石、铁矿石精矿和附聚物(包括烧结产品)中30质量%至72质量%的铁的浓度范围。

ISO 2597-2:2008 specifies two titrimetric methods, free from mercury pollution, for the determination of total iron content in iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chloride and titanium(III) chloride. The excess reductant is then oxidized by either dilute potassium dichromate (method 1) or perchloric acid (method 2).Both methods are applicable to a concentration range of 30 % by mass to 72 % by mass of iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
