Voltammetric determination of Pb2+ and Cd2+ with montmorillonite-bismuth-carbon electrodes
AbstractThe simultaneous determination of trace amounts of Pb2+ and Cd2+ with montmorillonite-bismuth-carbon electrodes was developed. Several parameters affecting the stripping current response were investigated and optimized. Under optimal conditions, the modified electrode showed a good linear response to Pb2+ and Cd2+ in the concentration range from 1 to 24μgL−1. The detection limits were 0.2μgL−1 for Pb2+ and 0.35μgL−1 for Cd2+. The proposed method was applied for determining Pb2+and Cd2+ contents in real water samples.
