Abstract
DPPH was tested with 36 cations in slightly acidic medium, in the presence, of EDTA but only vanadium(II) formed a stable red complex. Based on these effects a method was worked out for the selective spectrophotometric determination of vanadium(II) in the presence of the remaining tested cations. A comparison of the sensitivity and selectivity of this method with recently reported methods is presented.Keywords
