Iron ores. Determination of total iron content - Potentiometric titration methodWhat is ISO TS 25974 Determination of total iron content using potentiometric titration method about? ISO TS 25974 specifies a potentiometric titration method for the determination of total iron content of 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 potassium dichromate solution. This method is applicable to total iron
