摘要：

We have been investigating Fourier transform laser-induced photoacoustic spectroscopy (FT-LIPAS) for speciation of actinides in aqueous solution, and ultraviolet, visible and near-infrared photoacoustic spectroscopy (UV-VIS-NIR PAS) and Fourier transform infrared photoacoustic spectroscopy (FT-IR PAS) for speciation in the solid phase. These spectroscopic methods were applied to the speciation of uranium(VI) in NaHCO3/NaClO4 solution/precipitate systems. The results show that FT-LIPAS is capable of speciation of aqueous species at concentrations of 10(-4) M and that UV-VIS-NIR PAS and FT-IR PAS are useful for the speciation of the solid phase, especially for amorphous materials.
