GB/T 6609.10-2004 Chemical analysis methods and determination of physical performance of alumina Determination of vanadic oxide content-N-benzoyI-N-phenylhydroxylamine extraction photometric method (English Version)
This standard specifies the method for the determination of vanadium pentoxide in alumina. This standard applies to the determination of vanadium pentoxide content in alumina (copper less than 0.01%, chromium less than 0.65%). Measuring range: 0.0002% to 0.015%.
