Abstract:
Voltammetric behavior of the complex of vanadium with 2,3-dihydroxybenzaldehide in acid buffered solutions in the presence of bromate ions as an oxidant agent has been investigated. It has been established that the analytical signal amplifies by more than one order. The lowest concentration of vanadium determination with an accumulation time of 30 s is 2·10-10 М. The method has been used for determination of vanadium in natural waters.
