the adsorption catalytic current in a medium containingudchlorate and 8-hydroxyquinoline (exine) is suggested for theuddetermination of molybdenum(VI). Experimental conditionsudsuch as pH and the composition of supporting electrolyte have been optimized to get a linear calibration graph at trace levels of Mo(VI). The sensitivity for molybdenum can be considerably enhanced by this method. The influence of possible interferences on the catalytic current has been investigated. The sensitivity of the method is compared with those obtained for other DPP methods for molybdenum. A detection limit of 1.0 1Q-8 mol/L has been found.
