    Description / Table of Contents: Summary An AAS method is described for the direct determination of traces of copper in zirconium(IV) oxide chloride and nitrate. An interference study of the zirconium matrix is reported. Best conditions for the removal of the suppressive effect of zirconium on the copper signal by addition of hydrofluoric acid are described. Results obtained by analyzing commercial samples from different manufacturers are presented.
    Notes: Zusammenfassung Kupferverunreinigungen wurden in Zirkoniumoxidchlorid und -nitrat bestimmt. Störungen durch die Matrix wurden untersucht. Die abschwächende Wirkung des Zr auf das Cu-Signal wurde durch Zusatz von Fluorwasserstoffsäure beseitigt. Analysenergebnisse für verschiedene handelsübliche Zr-Salze werden mitgeteilt.
