Abstract: | An Ex‐situ antimony film screen‐printed carbon electrode (Ex‐situ SbSPCE) was successfully applied for the determination of Ni(II), by means of adsorptive stripping voltammetry using dimethylglyoxime as complexing agent, in a certified reference wastewater sample. This electrode is proposed as an alternative to more conventional antimony film electrodes. Ex‐situ SbSPCE was analytically characterized and the obtained parameters suggest that Ex‐situ SbSPCE behaves much better than both Ex‐situ BiSPCE and BispSPE for Ni(II) determination. The results confirm the applicability of Ex‐situ SbSPCE for the determination of low concentration levels of Ni(II) in natural samples with a very high reproducibility and good trueness. |
