Summary

The solubility of mercury(II) sulphide in the various reagents used to separate the copper-tin group has been quantitatively investigated. Our results show that with all reagents the solubility of mercury(II) sulphide is largest when tin(IV) and molybdenum(VI) are present and that the use of hydrogen peroxide with potassium hydroxide ensures that at least 95% of the mercury appears in the copper group.

Zusammenfassung

Die Löslichkeit von Queoksilber(II)-sulfid in den verschiedenen, zur Trennung der Kupfer-Zinn-Gruppe verwendeten Reagenzien wurde quantitativ überprüft. Diese Löslichkeit ist dann in allen Reagenzien am größten, wenn Zinn(IV) und Molybdän(VI) zugegen sind. Die Anwendung von Wasserstoffperoxid und Kalilauge gibt die Gewähr, daß mindestens 95% des Quecksilbers in der Kupfergruppe zu finden sind.
