Zusammenfassung

Die Bestimmung wird in ammoniakalischer Ammoniumtartrat- und Kaliumnitratlösung (pH ∼ 8,0–9,5) durchgeführt. Dabei wird das Oxydationspotential des Reagenses ausgenutzt. Durch Messung des kathodischen Stromes des reduzierbaren Ions (Cu2+) und des anodischen Stromes des Reagenses konnten die Bestandteile binärer Mischungen (z.B. Cu/Cd, Cu/Ni) gleichzeitig bestimmt werden. Das Verfahren ist schnell und liefert gut reproduzierbare Ergebnisse.

Summary

Copper, cadmium and nickel have been estimated amperometrically in ammoniacal ammonium tartrate and potassium nitrate (pH ∼ 8.0–9.5) using methyldithiobiuret as the titrant. The advantage of the oxidation potential of the reagent have been put to a practical use in these determinations. Furthermore, by the combined use of the cathodic current of a reducible ion (Cu2+) and the anodic current of the reagent simultaneous determination of the two components of binary mixtures (e.g., copper-cadmium and copper-nickel) in a single operation has also been achieved. The process is rapid and yields reproducible results within the limits of experimental errors.
