    Abstract

    A new method based on catalytic current in differential pulse polarogrms in a medium containing chlorate and -hydroxyquinoline (oxine) is described for the determination of tungsten.Experimental conditions such as pH and the composition of supporting electrolyte are optimized to get a linear calibration graph and also to lower the detection limit. The influence of possible interferences on the catalytic current has been investigated. The mechanism of the electrode process Is studied using DPP diagnostic criteria.
