GB/T 4698.12-2017 《Methods for chemical analysis of titanium sponge, titanium and titanium alloys—Part 12：Determination of vanadium content—Ammonium ferrous sulfate titration and inductively coupled plasma atomic emission spectrometry》 Related products
This standard specifies methods for the determination of vanadium content in titanium sponge, titanium and titanium alloys. The ferrous sulfate ammonium Titrimetric method is suitable for the determination of vanadium content between 1.00% and 25.00%, while the Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method is suitable for the determination of vanadium content between 0.010% and 15.00%. When the measurement ranges overlap, the ferrous sulfate ammonium Titrimetric method is used as an arbitration analysis method. The standard describes in detail the specific steps of sample treatment, oxidation and titration to ensure the accuracy of the determination of vanadium content.
