This paper describes the determination of Pb and Cu with a nafion – modified glassy carbon electrode and MnCo2O4 nanoparticles as working electrode for anodic stripping voltammetry.
Pb and Cu were accumulated in HCI / KCI ( 0.1 mol dm3 ) at a potential of – 1.4V ( us. AG / AGCI electrode ) for 480 s. followed by a linear sweep anodic stripping voltammetry ( ASV ) scan from – 1.0 to 0.5V.
Under optimum conditions, the calibration curves were linear in the range of 0.01 – 8 and 0.01 – 5 mg dm – 3 for Pb and Cu, respectively.
