<cfAbstr cfLangCode='EN' cfTrans='o'><p>The influence of bromate-ions on polarographic behavior of the complex of vanadium with 2,3-dihydroxybenzaldehide in acetate buffer solutions has been studied. In the presence of bromate-ions the analytical signal increases more than one order. The detection limit for the accumulation time of 30 s is 2&middot;10<sup>-10</sup>M. The method has been applied to determination of vanadium in the water of the Prut river.</p></cfAbstr>
