Determination of rare earth elements in mineral raw materials and rare earth industry products by neutron activation analysis
- 66 Downloads
To determine REE in mineral raw materials, high purity RE metals and their compounds, neutron activation analysis with extraction chromatographic REE separation has been developed. Combination of the developed RE extraction and separation procedures with subsequent γ-spectrometric analysis of the RE radionuclides allows to determine their content with the lower detection limit −10−5–10−8%. The relative standard deviation is 0.2–0.3.
