抄録

Laser-induced photoacoustic spectroscopy was used in a quantitative analysis of Pu in HNO<sub>3</sub> medium. Plutonium was quantitatively oxidized to Pu(VI) using Ce(IV). The photoacoustic measurement of Pu(VI) with maximum absorption at 830.5 nm was subsequently performed to determine the concentration. The photoacoustic signal was linearly proportional to the Pu(VI) ion concentration. The detection limit of Pu(VI) was estimated to be 0.5 µg mL<sup>-1</sup> (3<i>σ</i>) in 3 M HNO<sub>3</sub>. By the proposed method, Pu concentration was successfully determined in a nuclear waste solution for use in nuclear materials management.
