    The effect of acetate buffer concentration on the anodic stripping voltammetric response of carbon paste (macro)electrodes and microelectrodes

    The Square Wave Anodic Stripping Voltammetry response of in situ deposited Bi-film conventional size Carbon Paste Electrodes (CPEs) and generic microdisc carbon paste microelectrodes (CPμEs) in Pb(II) and Cd(II) solutions, has been studied as a function of acetate buffer concentration in the extended 0.001 M -0.5 M range. The advantages of microelectrodes (high ohmic tolerance and high mass transfer rates) allowed for the recording of good quality voltammograms at the CPμEs even at the lowest 0.001 M acetate levels studied, resulted in relatively higher voltammetric peaks and gave an optimum Pb and Cd signal in the 0.01-0.02 M acetate range.
