Antimony nanomaterials modified screen-printed electrodes for the voltammetric determination of metal ions

Evaluation of electrochemical performance of antimony modified screen-printed carbon electrodes

“…Following bismuth film electrodes (BiFEs), in 2007, antimony film electrodes (SbFEs) were reported by Hocevar et al as another functional and environmentally acceptable electrode material [15]. Compared to BiFEs, SbFEs exhibit comparable electroanalytical performance with extra advantages such as a relatively wide operational potential window associated with favorably hydrogen evolution and an unexpectedly low re-oxidation signal for the antimony itself [15][16][17][18][19]. Among other features, the antimony electrode revealed better performance in more acidic conditions (pH ≤ 2).…”

Electroanalytical performance of a Bismuth/Antimony composite glassy carbon electrode in detecting lead and cadmium

“…However, because of the toxicity of mercury and risks associated with its disposal there are severe restrictions on the use of mercury as an electrode material for stripping measurements [9]. Bismuth and antimony film electrodes have been used as an alternative to traditional mercury electrodes for electrochemical detection of heavy metals using stripping voltammetry techniques [9][10][11][12][13][14][15][16][17][18][19][20][21]. Bismuth-based electrodes offer attractive attributes in detecting heavy metals which include being environmentally friendly with low toxicity, simple preparation, high sensitivity, well-resolved stripping signals, a quite wide potential window which is necessary for stripping techniques, and insensitivity to dissolved oxygen.…”

Corrosion behaviour of heterogeneous antimony-copper layers in chloride media

“…Electrochemical investigations of antimony and antimony-rich alloys are relatively rare in the literature [18][19][20]. They are aimed towards the use of this element as an electrode for pH determination, stripping voltametric determination of trace metal ions and microcorrosion processes [21][22][23][24][25]. In the past, the anodic behaviour of pure antimony and its alloys has been studied in sulphuric acid environments related to their use as a positive grid in lead-acid batteries as well as in connection with the formation of antimony oxide with potential various applications as electroand photocatalysts, thin capacitive layers and electrochromic displays, etc.…”
