GB/T 6730.65-2009 《Iron ores - Determination of total iron content - Titanium(III) chloride reduction potassium dichromate titration methods（routine methods）》 Related products

This standard specifies the conventional method for the determination of total iron content in iron ore using titanium trichloride reduction potassium dichromate Titrimetric method, which is suitable for samples such as natural iron ore, iron concentrate, and sinters and pellets. The measurement range covers samples with total iron content of 25% to 72%. In the method, the sample is first reduced by titanium trichloride, and then titrated with potassium dichromate. The standard details the relevant instrumentation requirements and analytical steps to ensure the accuracy and Reliability of the determination results.
