Control analítico de cobres refinados por espectrometría de plasma ICP. II parte: Soluciones enriquecidas

Reference is made to Part I of this work where the possibilities of ICP plasma spectrometry for the analysis of high purity copper from direct solutions of the samples were studied. In order to improve the minimum contents which can be determined, it has been necessary to use enriched solutions. By means of five separation processes, all the elements considered are included: As, Sn, Sb, Bi, P, Ag, Zn, Fe, Mn, Ni, Pb, Cr, Cd, Se, and Te. The hydride generating system is also described for the determination of As, Sn, Sb, Bi, Se, and Te. Finally, a comparative study of the methods developed is presented
