GB/T 6730.8-2016 《Iron ores—Determination of iron(II) content—Potassium dichromate titrimetric method》 Related products
This standard specifies the use of potassium dichromate Titrimetric method for the determination of ferrous content in iron ores, iron concentrates, sinters and pellets, applicable to the range of 0.700% to 30.00%. Ferrous content can be obtained by dissolving the sample with acid and using the potassium dichromate Titrimetric method to determine the iron content in the solution. This standard also describes pretreatment methods for different samples to ensure the accuracy and Reliability of measurement.
