DETERMINATION OF TRACE URANIUM IN SOIL BY ISOTOPE DILUTION MASS SPECTROMETRY

  • The certain amount of soil is dissolved by HF-HClO_4 acid. The separation ofuranium from soil is obtained by TBP extraction chromatography. The trace uran-ium in common soil is measured by isotope dilution mass spectrometry. The resultof measurement is 1. 36μg/g.
