Abstract

An ion-chromatographic method, using a carbonate-buffered (1,2-cyclohexylenedinitrilo)tetraacetic acid (CDTA) eluant, is described for the simultaneous determination of vanadium(IV) and vanadium(V). Vanadium(IV) was, after pre-column complexation with CDTA, separated from vanadium(V) (as vanadate) by anion-exchange chromatography. The analytical range is 0.5 to 20 μg/ml and 0.25 to 10 μg/ml for vanadium(IV) and vanadium(V), respectively. Detection limits are estimated to be 145 and 70 ng/ml for vanadium(IV) and vanadium(V), respectively.
