A polarographic method is proposed for determination of vanadium in petroleum derivatives. The sample is first reduced to ashes. then the ashes are taken up in H/sub 2/SO/sub 4/ solution. purified by electrolysis. and subjected to polarography in alkaline solution. An anodic step is observed which corresponds to oxidation of V(IV) to V(V). The height of the step is proportional to the concentration of the metal. This method allows a sensitivity of 20 ppm and a precision of 2%. (tr-auth)
