20.500.12556/RUL-148304 Study of different types of copper electrodes for anodic stripping voltammetric detection of trace metal ions Copper electrodes exhibit interesting characteristics for application in electrochemical stripping analysis and represent another alternative to their mercury counterparts. In this work, we studied different types of copper-based electrodes for anodic stripping voltammetric detection of trace metal ions. We investigated copper film (CuFE), and bulk copper electrodes, such as in-situ and ex-situ prepared CuFEs using glassy carbon and screen-printed carbon supporting electrodes, a bulk copper disk and screen-printed copper electrode, and a copper wire as the simplest, inexpensive, and readily available analog. For studying their electroanalytical performances, low concentrations (μg L$^{−1}$) of Cd(II) and Pb(II) were used as model ions. We examined and optimized several key parameters affecting the preparation and functioning of copper electrodes, such as the composition of the measurement solution, copper concentration for in-situ and ex-situ preparation of CuFE, deposition potential, deposition time, etc. Most of the tested copper electrodes showed favorable stripping voltammetric performances, particularly the CuFE ex-situ prepared on a glassy carbon electrode and the CuFE in-situ prepared on a screen-printed carbon substrate. Notably, a copper wire revealed an excellent electroanalytical operation with a limit of detection of 0.6 μg L$^{−1}$ for Pb(II) and 1.8 μg L$^{−1}$ for Cd(II). The practical applicability of a copper electrode was tested by measuring a real tap water sample. copper film electrode copper bulk electrode copper wire electrode lead cadmium anodic stripping voltammetry bakrove elektrode priprava elektrodnih površin določanje svinca določanje kadmija anodna striping voltametrija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-08-11 09:00:07 2023-08-11 09:00:08 2025-08-08 13:22:30 0000-00-00 00:00:00 2023 0 0 11 str. art. 142480 Vol. 457 20 Jul. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 543.552 1873-3859 10.1016/j.electacta.2023.142480 151348483 1-s2.0-S0013468623006588-main.pdf 1-s2.0-S0013468623006588-main.pdf 1 90C83492BA7B3B3EF7F369C3ED9CA1C4 c6b820e99e40055963c90676654e38e956dde89b720913faeabb7d03a3b897fd 4a1ee21e-3815-11ee-b9d7-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172396 https://www.sciencedirect.com/science/article/pii/S0013468623006588 1 b41b7de4-3814-11ee-b9d7-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172395 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
