GB/T 6730.6-2016 《Iron ores—Determination of metallic iron content—Ferric chloride-sodium acetate titrimetric method》 Related products
This standard specifies the use of ferric chloride-Sodiumacetate Titrimetric method for the determination of metallic iron content in iron ores, iron concentrates, sinters and pellets, with a determination range of 0.150% to 3.00%. Methods The nonmagnetic substances are separated by magnetic separation, and then the ferric chloride-Sodiumacetate buffer solution is used to selectively dissolve metallic iron. Finally, the titration is carried out using the potassium dichromate standard titration solution. This standard describes the sample preparation, reagent use and operation steps in detail to ensure the accuracy of the determination results.
