USE X-RAY RADIOMETRIC METHOD FOR DETERMINATION OF LIGHT LANTHANIDES IN THE SOILS
https://doi.org/10.19047/0136-1694-2010-66-83-92
Abstract
The technique of X-ray fluorescent energy dispersion method - X-ray radiometric analysis using 241Am isotope source for identification of lanthanides: praseodymium, neodymium and samarium - has been developed. The method is based on the elimination of barium distortion and lanthanum on the praseodymium and neodymium line, as well as the effects of lanthanum and selenium on the samarium line. On the basis of the new method it is possible to obtain mass data on the geochemistry of light lanthanides in soils.
