Abstract
Three organic molecules were used as modifiers of carbon paste electrodes (CPEs) for the analysis of different metals (Pb2+, Cd2+ and Cu2+) by using Square Wave Voltammetry (SWV) technique. The effect of the modified electrodes (MO-CPEs) on the electrochemical behavior has been shown. The MO-CPEs gives the more sensitivity. The detection limits obtained in all analysis approaching 10-8 mol/L.
