Application of laser-induced fluorescence for determination of trace uranium, europium and samarium.

Abstract

Trace amounts of uranium, europium and samarium can be determined by means of laser-induced fluorescence. The fluorescence emission and excitation spectra were observed by adding fluorescence enhancing reagents. The fluorescence lifetimes of these elements were also measured. The intensities of emission were found to be linear with respect to the concentration of the element over a wide range. The detection limits for U(VI), Eu(III), and Sm(III) were established as 0.05, 0.1, and 10 ng/ml, respectively. The study suggested that this is a suitable technique for the trace determination of uranium and rare earth elements.
