Summary

A potentiometric method is described for the determination of Bi(III), Cu(II), V(V) and Cr(VI) in alkaline glycerol medium by ferrous sulphate solution. Errors are below ±1.5%. Furthermore, the Fe(II)-glycerol complex is used for the detection of Ag(I), Au(III), Bi(III), Cn(II), Hg(II) and Pd(II).

Zusammenfassung

Ein Verfahren zur potentiometrischen Bestimmung von Bi(III), Cu(II), V(V) und Cr(VI) in alkalischer Glycerinlösung mit Fe(II)-Lösung wird mitgeteilt. Die Fehler liegen unter ± 1,5%. Au\erdem wird eine Nachweismethode für Ag(I), Au(III), Bi(III), Cu(II), Hg(II) und Pd(II) beschrieben, die ebenfalls auf der Reduktion mit Hilfe des Fe(II)-Glycerinkomplexes beruht.
