15 The electroanalytical technique Absence of Gradients and Nernstian Equilibrium 16 Stripping (AGNES) has been extended by applying stripping chronopotentiometry 17 (SCP) as the reoxidation stage in the determination of the free concentration of Zn 2+ , 18 Cd 2+ and Pb 2+ . This new approach, called AGNES-SCP, has been implemented with 19 screen-printed electrodes (SPE) and the standard Hangin...

electrochemical properties of various rock-shaped-cuo/graphite (g) composites and monoclinic structure cuo nanoparticles as the cathode versus a zinc plate as the anode in a 4m naoh electrolyte were elucidated by electrochemical impedance spectroscopy (eis) and chronopotentiometry (cp) in a two electrode configuration cell. various values of g 9, 16 and 28 wt% were prepared and studied as catho...
