Summary

A special method for sample preparation avoiding losses of mercury is described. A rotating gold electrode is used for the anodic-stripping voltammetric determination of mercury. In order to suppress base-line disturbances, the signal of the 2nd harmonic wave of AC-voltammetry is employed.

Zusammenfassung

Es wird ein spezielles Verfahren zur Probenvorbereitung beschrieben, durch welches Verluste an Quecksilber weitgehend vermieden werden. Die invers-voltammetrische Bestimmung des Quecksilbers erfolgt an einer rotierenden Goldelektrode. Durch Messung der Signale der 2. harmonischen Welle der Wechselstrom-Voltammetrie werden Störungen der Grundlinie weitgehend eliminiert.
