Study on the Separation of Sm and Nd from Silicates for Isotopic Dilution Measurement |
| |
| Abstract: | The procedure includes two steps, the first is extracting REE from the
rocks, and the second is the separation of Nd and Sm from other REE and
separation of Sm and Nd from each other with strong acidic cation resins.The
effect of the above separation procedure were checked up by means of radio
activity and mass spectrometer. |
