Mercury Ion Monitoring in Mercury Plating Bath by Anodic Stripping Voltammetry

초록

Anodic stripping voltammetry (ASV) is successfully applied in mM level detection of mercury ion in an electroplating bath which is currently used in preparing a cathodic electrolyzer. Glassy carbon electrode is used for the detection and the optimum condition obtained is 10 s deposition at - 1.4 V vs. Ag/AgCl and stripping by scanning from - 1.4 to + 0.4 V vs Ag/AgCl at 50 mV/s. By applying the method, the mercury ion concentration in the electroplating bath could be successfully monitored during the plating.
