Summary

Conditions have been worked out for the reductometric determination of MnII with cobalt(II)-nitrate solution in a medium of triethanolamine, cyanide and hydroxide. A large excess of cobalt and a number of other common elements does not interfere in this determination, which is well suited for practical purposes. The error is below 1%.

Zusammenfassung

Eine Methode wurde ausgearbeitet zur reduktometrischen Bestimmung von MnII mit Kobalt(II)-nitratlösung in Gegenwart von Triäthanolamin, Cyanid und Hydroxid. Ein großer Überschuß an Kobalt und eine Anzahl anderer Elemente stören diese für praktische Zwecke geeignete Methode nicht. Der Fehler ist kleiner als 1%.
