The application of a square-wave polarograph to small amounts of plutonium in hydrochloric and nitric acid solutions was studied. Plutonium concentrations below 10/sup -5/ mole per liter were determined in these acids with a stationary platinum electrode. The derivative wave heights were proportional to concentration as predicted by the square-wave theory. Half-wave reduction potentials obtained for the plutonium(IV) to (III) couple agree with accepted values. The method exhibits higher sensitivity than conventional polarography, no effects from sample agitation, and negligible effects from irreversibly reduced materials, such as oxygen, on the measurement of plutonium ions.
