The Fabrication and Characterization of a Bismuth Nanoparticle Modified Boron Doped Diamond Electrode and Its Application to the Simultaneous Determination of Cadmium(II) And Lead(II)

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 rnM Bi(NO3)(3) in 0.1 M HClO4, (pH 1.2), and gave detection limits of 1.9 mu g L-1 and 2.3 mu g 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. In situ atomic force microscopy (AFM) was performed to characterize the Bi nanoparticle growth on the BDD surface over a period of 120 s. The average final size of the Bi nanoparticles was 45 +/- 25 nm in height with a number density on the electrode surface of ca. 7 x 10(9) np/cm(2) obtained. The in situ AFM characterization suggests that the Bi nanoparticles are deposited by an "instantaneous" nucleation and growth mechanism.
