“…During the development of ASV over the past 50 years, mercury film electrodes (MFE) and hanging mercury drop electrode have been used due to their high sensitivity and remarkable reproducibility [3][4][5]. Due to its toxicity, the traditional mercury drop electrode is being progressively replaced by modified glassy carbon electrode and screen-printed electrodes [6,7] Wang et al [8] found that bismuth presents analogous analytical performance when compared to mercury for stripping analysis.…”

In this work, we report the simultaneous determination of cadmium and lead using glassy carbon electrodes (GCE) modified by poly(3,4-ethylenedioxythiophene) (PEDOT) for linear sweep anodic stripping voltammetry (LSASV). The modification allows metal detection without involving oxygen removal, mechanical stirring and introduction of alloying additions such as Hg, Bi, Sb, etc. during the pre-concentration step. Introduction of poly (4-styrenesulphonate) (PSS) as dopant in the PEDOT matrix improves reproducibility, stability and sensitivity in the detection. Both cadmium and lead peaks were readily quantifiable over the linear range of 2 - 10 ?g/ml and the detection limit being 1.47 ?g/ml and 1.15 ?g/ml respectively. The calibration plot shows a linear response with correlation coefficient of 0.9911 and 0.9944 for cadmium and lead respectively. Thus, the GC/PEDOT/PSS modified electrode suggested as a suitable matrix for rapid monitoring of these heavy metals at trace levels

We report the simultaneous electroanalytical determination of Pb2+ and Cd2+ by square-wave anodic stripping voltammetry (SWASV) using a bismuth nanoparticle modified boron doped diamond (Bi-BDD) electrode. Bi deposition was performed in situ with the analytes, from a solution of 0.1 mM Bi(NO3)3 in 0.1 M HClO4 (pH 1.2), and gave detection limits of 1.9 µg L-1 and 2.3 µg L-1 for Pb(II) and Cd(II) respectively. Pb2+ and Cd2+ could not be detected simultaneously at a bare BDD electrode, whilst on a bulk Bi macro electrode (BiBE) the limits of detection for the simultaneous determination of Pb2+ and Cd2+ were ca. ten times higher
