Abstract: Screen printed electrodes plated with bismuth were used to record anodic stripping voltammograms of Pb(II), In(III) and Cd(II). Using two bismuth precursors: Bi2O3 dispersed in the electrode body and Bi(III) ions spiked into the tested solution it was possible to deposit bismuth layers, demonstrating exceptional ability to accumulate metals forming alloys with bismuth. The voltammetric signals were amplified by adjusting the electrode location with respect to rotating magnetic field. The electrode response was influenced by vertical and horizontal distance between the magnet center and the sensing area of screen printed electrode as well as the angle between the magnet surface and the electrode. When the electrode was moved away from the magnet center the recorded peaks were increasingly smaller and almost not affected by the presence of bismuth ions. It was shown that to obtain well-shaped signals a favourable morphology of bismuth deposits is of key importance. Hypotheses explaining processes responsible for the amplification of voltammetric signals were proposed.

 

Keywords: Screen printed electrodes, Anodic stripping voltammetry, Bismuth precursors, Bismuth film electrode.
