Abstract
For the first time, a carbon screen-printed electrode modified in-situ with lead film (PbF-SPCE) was used for the adsorptive stripping voltammetric determination of Co(II) and Ni(II) in the form of DMG complexes, or Co(II) in the form of a complex with nioxime. Lead film was electrochemically generated in-situ on a commercially available three-electrode screen-printed electrochemical strip from a 0.2 M ammonia buffer solution (pH 8.7) containing 5·10-5 M Pb(NO3)2 and DMG or nioxime. The LOD of the elaborated AdSV procedure with nioxime is equal to 0.003 μgL-1 Co (for tacc = 120 s), which is significantly lower than the LOD values of the vast majority of anodic stripping procedures for other elements (e.g. Pb, Cd, Zn, Cu) at Bi, Sb and Sn films electrodes. Moreover, the separation of Ni(II) and Co(II) peaks in the presence of nioxime was even better at the PbF-SPCE than at the hanging mercury drop electrode.
