How to remove the chelate formed during the determination of vanadium by tantalum reagent extraction spectrophotometry

Thread Content

The vanadium sample reacts with the tantalum reagent extract in the presence of strong acids, and a peach-colored chelate is formed. How can this chelate be removed? Are there any viable methods? Thank you!

The ratio of the extract is incorrect, or there is a problem with the reagents

It’s the method specified by national standards; there’s no issue with the extract
