GB/T 13747.18-2022 《Methods for chemical analysis of zirconium and zirconium alloys—Part 18：Determination of vanadium content—N-benzoyl-N-phenyl hydroxylamine spectrophotometry and inductively coupled plasma atomic emission spectrometry》 Related products

This standard provides two methods for the determination of vanadium content in zirconium and zirconium alloys. Spectrophotometric method, spectra-trophotometry is suitable for vanadium content in the range of 0.002% to 0.020%. Vanadium content is quantified by measuring the Absorbance of the red complex formed with benzoylphenylhydroxylamine at 530 nm. Inductance-coupled plasma atomic emission spectroscopy (AES) is suitable for vanadium content in the range of 0.005% to 0.020%, using atomic emission spectroscopy (AES) to detect vanadium content. These methods are suitable for the analysis of vanadium content in sponge zirconium, zirconium and its alloys, providing detailed operation steps and reagent requirements for accurate determination.
