| Abstract: | In situ bismuth film modified carbon fiber
microelectrode is reported for sensitive detection of Cd(II) and Pb(II) in 0.1 M acetate buffer solution of pH 4.5. As compared to the unmodified
electrode, in situ bismuth
modification improves the detection limit at nanomolar level for individual as
well as simultaneous detection of Cd(II) and Pb(II). Electroanalysis
carried out using square wave anodic stripping voltammetry shows linear
response over the 50-500 nM range.
The minimum detection limits are not affected for the individual and
simultaneous metal detection. Using the standard addition method, cadmium and
lead have been detected in tap water samples successfully. |
