| Abstract: | An EDXRF
technique for the determination of four important rare earth impurities, viz.,
Eu, Dy, Sm and Gd, at 20-1000  g/ml in aqueous medium as well as in the presence of
uranium has been reported. The conditions have been optimized for the
simultaneous determination of these elements. The limits of detection for the
analytes in aqueous solutions are determined to be 20 g/ml. In order to achieve
lower limits of detection, a novel method based on polyvinyl alcohol films
containing these rare earths has been established. Four uranium oxide samples
have been analysed by EDXRF as well as inductively coupled plasma–atomic
emission spectrometry after chemical separation of uranium. The results are in
good agreement. |
