Characteristics of solid amalgam electrodes different from HMDE
Josypčuk, Bohdan ; Navrátil, Tomáš
In the contribution are shown the results of experiments realized with solid amalgam electrodes containing, apart from mercury, also Ag, Cu, Ir, Au, Bi, or Cd. These results differ from those obtained with the hanging mercury drop electrode (HMDE). In some cases the solid amalgam electrodes enable the study of properties of compounds, which can not be observed on HMDE, usually due to the anodic dissolution of mercury. Anodic stripping voltammetry of Zn(II), Cd(II), Pb(II), Cu(II), and Fe(III), cathodic stripping voltammetry of adenine, guanine, phytochelatins, sulfides, and catalytic processes in presence of hydrogen peroxide, alcohols and Os-modified DNA, were studied with the working amalgam electrodes.
