Smith, M E

A polarographic method for the determination of vanadium in the presence of plutonium has been devised which does not require a separation of the plutonium. Hydrochloric acid solutions containing both plutonium and vanadium are treated with zinc and zinc amalgam prior to analysis in order to reduce both metals. The plutonium is reduced to the (III) state and the vanadium chiefly to the (II) state. The height of the anodic wave produced by the oxidation of the vanadium is proportional to the total vanadium concentration. Plutonium(III) does not produce an interfering wave. Solutions of V/Pu weight ratio as low as 6.4 x 10(exp {minus}4) may be analyzed by this method with a reproducibility of 3.4% for the 95% level.
