Abstract
AbstractThe voltammetric behavior of a bismuthiol I‐containing carbon paste electrode was studied. Bismuthiol 1 is electroactive, when mixed with carbon paste as an electrode modifier, and is oxidized at 0.3 V and re‐reduced at −0.6 V (vs. SCE). Nevertheless, it can be used as a modifier of carbon paste electrodes for the preconcentration and subsequent voltammetric measurement of bismuth, if suitable measurement conditions for the analysis are met. Bismuth(III) can be preconcentrated from acidic solutions onto this electrode under open circuit conditions. Linearity between current response and concentration can be achieved for 0.005 to 4 μg/ml bismuth using cathodic differential pulse voltammetry after preconcentration for 0.5 or 2 minutes. The interferences as well as various parameters for the preconcentration and measurement of bismuth(III) were investigated.
