Linear sweep anodic stripping voltammetry (LSASV) and differential pulse anodic stripping voltammetry (DPASV) have been used for the simultaneous determination of In and Cd in hydrochloric acid-based media at the hanging mercury drop electrode (HMDE), mercury-, and bismuth-plated glassy carbon electrode (MF-GCE and BiF-GCE, respectively). The main focus of the study was concentrated on the resolution of In- and Cd-signals achieved by means of the three investigated working electrodes. Whereas the LSASV as well as DPASV signals for indium and cadmium almost overlapped when using the HMDE, the corresponding In- and Cd-peaks were well-separated at both MF-GCE and BiF-GCE. In addition, at the latter film electrode, a typical resolution as well as the sensitivity of the respective stripping signals were even superior to those evaluated for the MFE. Based on the results obtained, the possibilities and limitations of the individual elctrodes are outlined with particular emphasis on the bismuth film-plated electrode substrate.
