Abstract

Laser-induced photoacoustic spectroscopy (LPAS) is a new technique for the chemical speciation of aquatic transuranium (TRU) ions in very dilute concentrations. The first part of this paper deals with the principles, instrumentation and characteristics of LPAS in an aqueous solution and presents specific examples. The theoretical estimation of the speciation sensitivity is demonstrated and compared with experimental sensitivity values. The second part deals with the spectral work in an aqueous solution and with the use of LPAS for the speciation of TRU ions in groundwater. Examples presented include hydrolysis reaction, complexation and colloid generation of the Am(3+) ion. Speciation sensitivities of U, Np, Pu and Am of different oxidation states in a variety of aqueous solutions are summarised.
