| Abstract: | The separation of rare earth impurities in high purity erbium oxide have been carried out with P507 extration chromatography. Hydrochloric acid-Ammonium chloride serves as eluant.The method of preconcentration and the determination condition of spark source mass spectrometry (SSMS) have been selected. The measured purity of erdium oxide is up to 99. 9999%. |
