TL;DR: In this article, Bismuth coated glassy carbon electrodes have been applied to the square-wave anodic stripping voltammetry (SWASV) of trace concentrations of tin.
Abstract: Bismuth coated glassy carbon electrodes have been applied to the square-wave anodic stripping voltammetry (SWASV) of trace concentrations of tin. Optimization of Bismuth Film Electrode (BFE) performance was conducted after initial comparison with the more traditional mercury electrode. Simultaneous deposition of tin and bismuth at −1.3 V for 2 minutes in a supporting electrolyte of 2.5 M sodium bromide utilizing a square-wave stripping step, allowed analysis of tin at the μg L−1 level. Parameters, such as deposition potential and time, bismuth concentration, square-waveform settings including amplitude, step height and frequency were studied and optimized. The dependence of stripping current on deposition time indicates that using longer deposition time should facilitate sub μg L−1 analysis. Tin was analyzed simultaneously with cadmium and either indium or thallium; Where as lead and copper were not resolved from the stripping peaks of tin and bismuth respectively. Finally, the method was applied to the analysis of tin in fruit juice.
