    Abstract

    The determination of vanadium(V) by differential pulse polarography (DPP)based on adsorption catalytic current in a medium containing cupferron and bromate is described. Experimental conditions such as pH and the composition of supporting electrolyte are optimized to get maximum peak current as well as a linear calibration graph at low vanadium concentrations. The sensitivity for vanadium determination is considerably enhanced by this method. The influence of possible interferences on the adsorption catalytic current has been investigated. Based on the results obtained in this study, a suitable mechanism is proposed for the electrode process.
