Abstract

A laser induced photoacoustic spectroscopy (LPAS) is developed for the microscopic speciation of actinides in natural aquatic solution. By introducing special detection instrumentation and signal processing system, a differential measurement of sample and reference solutions is realized. The LPAS provides a normal spectral work comparable to conventional absorption spectroscopy, only with the higher speciation sensitivity, e.g. 10**-8 mol L**-1 for the Am(III) ion. Applications of the LPAS are demonstrated for the speciation of oxidation state, hydrolysis reaction, complexation and colloid generation of actinide ions in micro or submicromole range in pure solutions as well as natural groundwaters.
