Ex-situ antimony screen-printed carbon electrode for voltammetric determination of Ni(II) - ions in wastewater
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 al...

| Summary: | 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. |
