In this article, the field of mercury film electrodes (MFE's) as electroanalytical devices is reviewed. Special emphasis is placed on the area of new materials as substrates for the mercury coating and the mercury plating process as well as on the developments related to the electrode modification used to achieve an increase in either the selectivity and/or the sensitivity of the analysis. Other topics discussed are microelectrodes, disposable electrodes and some novel, innovative or less well explored applications of electroanalytical methods using MFE's. The future prospects, potential uses and alternatives for MFE's in electroanalysis are finally discussed.read more

High-sensitivity determination of lead and cadmium based on the Nafion-graphene composite film.
TL;DR: It is found that the prepared Nafion-G composite film not only exhibited improved sensitivity for the metal ion detections, but also alleviated the interferences due to the synergistic effect of graphene nanosheets and Nafions.

Insights into the anodic stripping voltammetric behavior of bismuth film electrodes
TL;DR: In this paper, the bismuth-coated electrode is shown to be prone to errors caused by the formation of Cu-Zn intermetallic compound, that can be circumvented by the addition of gallium, in a manner analogous to mercury film electrodes.
