Abstract

The presented work shows the preparation of screen-printed electrodes modified with a lead (PbF-SPE) film for adsorptive stripping voltammetric determination of cobalt ions in real samples. The metallic film was deposited in situ on the surface of the graphite SPE (GSPE). The conditions for the determination of cobalt in the form of dimethylglioximate complexes, including the concentration of the complexing agent and the instrumental parameters, were optimized. The limit of detection for cobalt determination was 3.8 ng/mL. These studies were complemented with a voltammetric characterization by using the reversible redox couple ferrocyanide/ferricyanide, to assess for the investigation of each step of the analytical procedure for the metal-based platform.
