Studies of the Voltammetric Determination of Trace Metals in Seawater.

摘要

The basic voltammetric cell consists of the analyte whole metal concentration is to be determined and three electrodes. During the cathodic deposition mode, metal ions are reduced by the potential at the working electrode and deposited on the mercury film at the electrode surface as a metal-Hg-amalgam. The potential at the working electrode is induced by the polarograph through the counter electrode with the reference electrode taken as zero. The actual potential of the working electrode depends upon the type of reference of electrode used. (Author)
