Solvent Extraction of Vanadium (V) with N-Benzoyl-N-phenylhydroxylamine
Get PDFN-Benzoyl-N-phenylhydroxylamine is a monomeric solute in
chloroform which readily extracts vot from acidic aqueous solutions.
The vanadium species extracted from concentrated aqueous
acid solutions have a characteristic absorption band at 450-550 mμ.
Solvent extraction experiments indicate that from aqueous 1-6
N HCl two vanadium species are extracted into chloroform. The
compositions of these species correspond to the reagent: vanadium:
chloride ratios of 2 : 1 : 1 and 3 : 1 : 1
