Abstract

The Schiff base formed from salicylaldehyde and anthranilic acid has been found to be a specific and sensitive reagent for the spectrophotometric determination of vanadium (V). This reagent forms a violet ester with vanadic acid (at pH = 1) extractable with benzene. The determination can be carried out in the presence of many diverse ions, and all but ferric ions do not interfere. Phosphoric acid is used both for masking the iron III and to make the extraction easier. The limit of identification is 10 μg vanadate/1 ml.
