中文名称：铁矿石 总铁含量的测定 第2部分：氯化钛（III）还原后滴定法

英文名称：Iron ores — Determination of total iron content — Part 2: Titrimetric methods after titanium(III) chloride reduction

标准范围

This part of ISO 2597 specifies a titrimetric method, free from mercury pollution, for the determinationof 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 dilutepotassium dichromate.This method is applicable to a concentration range of 30 % mass fraction to 72 % mass fraction of ironin natural iron ores, iron ore concentrates and agglomerates, including sinter products.
