Determination of vanadium content in vanadium carbide
Vanadium carbide is an important alloy additive, which can improve the corrosion resistance, wear resistance, strength and other comprehensive properties of hard alloys, so it is widely used in alloys. At present, the main methods for the determination of high vanadium content are REDOX titration, inductively coupled plasma atomic Emission spectrometry (ICP-AES), X-ray fluorescence spectrometry and spectrophotometry, but they all have their shortcomings. Chemical titration is widely used because of its high accuracy, easy to master and low operating [...]
