| Abstract: | The separation of rare earth impurities in high purity gadolinium oxide have been carried out with 2-ethylhexyl hydrogen- 2-ethylhexyl phoshonate (P507) extraction chromatography ; hydrochloric acid-ammonium chloride serves as eluant. The method of preconcentration and the determination conditions of spark source mass spectrometry have been selected. The measured purity of gadolinium oxide is up to 99.9999 %. |
