Abstract

Laser-induced photoacoustic spectroscopy (LPAS) has been developed for the direct speciation of actionoids in solution with the minimal disturbance of species equilibria. The speciation of actinoids is defined as the elucidation of the individual physical and chemical forms of actinoids in a sample. In the present review, the characteristics of the optical absorption spectra of actinoids, theprinciple, theory, and construction of the LPAS system are described in detail with its application to the speciation of actinoids in aqueous solution.
