Ex-situ antimony screen-printed carbon electrode for voltammetric determination of Ni(II) - ions in wastewater Barceló, Cristian Serrano i Plana, Núria Ariño Blasco, Cristina Díaz Cruz, José Manuel Esteban i Cortada, Miquel Níquel Voltametria Anàlisi electroquímica Nickel Voltammetry Electrochemical analysis 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. 2019-09-05T12:06:19Z 2019-09-05T12:06:19Z 2015-10-28 2019-09-05T12:06:20Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1002/elan.201500511 Electroanalysis, 2015, vol. 28, num. 3, p. 640-644 https://doi.org/10.1002/elan.201500511 (c) Wiley-VCH, 2015 info:eu-repo/semantics/openAccess Wiley-VCH Articles publicats en revistes (Enginyeria Química i Química Analítica)
