dc.description.abstract | Exfoliated β-Sb or two dimensional (2D) antimonene-based modified screen-printed electrode (2D Sb-SPCE), prepared by drop-casting of an exfoliated layered β-antimony (2D Sb) suspension, was used for the simultaneous determination of Pb(II) and Cd(II) by differential pulse anodic stripping voltammetry (DPASV). 2D Sb-SPCE was characterized by microscopic and analytical techniques, and compared not only to bare SPCE but also to layered antimony chalcogenides based-sensors. Both Sb2S3 and Sb2Se3 have an isomorphous tubular one-dimensional (1D) crystal structure, whereas Sb2Te3 and monoelement β-Sb have a 2D layered structure. Under optimized conditions, 2D Sb-SPCE displays an excellent analytical performance with detection limits of 0.3 and 2.7 μg L−1 for Pb(II) and Cd(II), respectively, and a linear response from 1.1 to 128.3 µg L−1 for Pb(II) and from 9.1 to 132.7 µg L−1 for Cd(II). Moreover, 2D Sb-SPCE was successfully applied for the DPASV determination of Pb(II) and Cd(II) in tap water, achieving statistically comparable results to those provided by ICP-MS measurements. | - |
