The experimental conditions for the preparation of the DMG-SPCE sensor were optimized by means of a D-optimal design, and the built sensors were analytically evaluated for the determination of Ni(II) by adsorptive stripping voltammetry (AdSV). Its analytical performance suggests its suitability for the determination of Ni(II)-ions by AdSV at concentration levels of μg L-1 (LOD of 2.3 μg L-1, linear range from 7.6 to 200 μg L-1). Finally, the applicability of the developed sensor was assessed by the determination of trace levels of Ni(II) by AdSV in a wastewater reference material with a very high reproducibility (0.005 %) and good trueness (0.1 %).7 p.application/pdfengcc-by-nc-nd (c) Elsevier B.V., 2019http://creativecommons.org/licenses/by-nc-nd/3.0/esNíquelVoltametriaAnàlisi electroquímicaElectroquímicaNickelVoltammetryElectrochemical analysisElectrochemistryinfo:eu-repo/semantics/article6892762019-09-06info:eu-repo/semantics/openAccess
