The oxidation-state specific detection of actinide ions, U(VI), Pu(IV), Pu(VI), and Am(III), was investigated by pulsed laser photoacoustic spectroscopy. With a single-beam differential technique, the solvent effect is compensated and thus the detection sensitivity substantially increased. The observed detection sensitivities are8×10–7M/L for U(VI)7×10–8M/L for Pu(IV)3×10–8M/L for PU(VI)2×10–8M/L for Am(III)The present method facilitates the study of complexation and polymerization of actinide ions in the submicromole concentration range. |
