摘要: A commercially available sputtered bismuth screen-printed electrode (BispSPE) has been pioneeringly applied for the simultaneous determination of Cd(II) and Pb(II) ions in a certified groundwater sample by means differential pulse anodic stripping voltammetry (DPASV) as an alternative to more conventional carbon electrodes (BiSPCEs). BispSPEs can be used large set measurements without any previous plating or activation. The obtained detection quantification limits suggest that produce better analytical performance compared In-situ BiSPCE determination, but also Ex-situ determination. results confirm applicability these devices low level concentrations metal natural samples with very high reproducibility (0.7% 2.5% respectively), good trueness (0.3% 2.4% respectively).
