| Abstract: | High-purity iridium matrixes used in spectral analysis were developed to meet the request of the new national standards to iridium standard samples.The technological flow of high-purity Ir matrixes for spectral analysis was determined through experimental study.The process was comprised of removing base metal cations by P204 solvent extraction,removing precious metal impurities in the form of complex anions by N235 solvent extraction,removing Rh and other metal impurities by H2 reducing in solution,removing... |
