Abstract :

<p><p> Poly (3,4ethylenedioxythiophene) (PEDOT), Polyanthranilic (PANA) acid and its co–polymer (PEDOT –ANA) modified electrodes have been prepared for the analysis of cadmium and lead metals cations in formulated samples using Anodic Stripping voltammetry (ASV) technique. The electrodeposition was performed using cyclic voltammetry from acidic solution containing appropriate monomer concentrations and sodium dodecyl sulphate (SDS) as a wetting agent. The structure and the surface morphology of the obtained polymers films were characterized using IR spectroscopy and a scanning electron microscope. In the electrochemical analysis of Pb (II), and Cd (II), very good responses have been observed for both metals with all modified electrodes employed. However, the poly(3,4ethylenedioxythiophene)–co–anthranilic acid modified electrode has resulted in very low detection limits. The Cd (II) detection limits for all the modified electrodes were 3.7 µM, 0.7 µM and 0.6 µM and for Pb (II) were 1.25 µM, 0.625 µM and 0.125 µM at PEDOT, PANA and PEDOT –ANA electrodes respectively</p></p>
