“…when Sb(III) ions can not be added to the medium (in environmental or in-vivo measurements); or in metal complexation studies, where the presence of Sb(III) ions in the medium can completely disturb the speciation of the system [6,8] [8,11,18,[26][27]29]. GCE surface can be also modified with 5 % Nafion solution prior to the modification with Sb [27]. As can be seen in Table 1, the studies using an ex-situ SbGCE focus on both the determination of heavy metal ions [8,27,29], and the measurements of organic compounds such as dopamine and ascorbic acid [11], pantoprazole [26] and sulfasalazine [18], in which ex-situ SbGCE reveals a better electroanalytical performance than ex-situ BiGCE and bare GCE.…”

This review summarizes analytical determinations carried out using antimony film electrodes (SbFEs), an environmentally safe option that constitutes an alternative not only to the most conventional Hg-based electrodes but also to Bi-based electrodes. SbFEs offer some interesting characteristics such as favorably negative overvoltage of hydrogen evolution, wide operational potential window, convenient operation in acidic solutions of pH 2 or lower and a very small Sb stripping signal. The substrate on which the Sb was plated is used to classify the types of SbFEs. Moreover, we detail the method of coating the substrate with Sb as well as the Sb modifiers. We present tables with the most important information from the accessible literature.

“…Film electrodes, in situ or ex situ prepared with mainly bismuth, but also of copper, lead and tin, have been also explored (Ariño et al, 2017;Jovanovski et al, 2015Jovanovski et al, , 2017Economou, 2005;Petovar et al, 2018;Czop, 2011;Korolczuk et al, 2005). Several research groups have also reported on the use of in situ and ex situ prepared antimony film electrodes (SbFE) for trace heavy metal determination (Serrano et al, 2016) in either 0.01 M HCl solution (Hocevar et al, 2007;Bassie et al, 2013;Ashrafi and Vytřas, 2012;Vasko and Bozidar, 2009) or in 0.1 M acetate buffer (Bassie et al, 2013;Arancibia et al, 2013;Maczuga et al, 2013).…”

Glassy carbon electrodes (GCE) have been extensively employed for the determination of trace amounts of heavy metals. Lately, modifications of GCE are currently being sought. One way of obtaining better analytical performance compared to GCE is the employment of an in situ prepared antimony-film glassy carbon electrode (SbFE). This combination is especially attractive in anodic stripping voltammetry technique which uses square wave excitation signal. This work will report on the optimization of the in situ prepared SbFE by employing different deposition potentials. Furthermore, a preliminary study using electrochemical impedance spectroscopy (EIS) was performed at different deposition and measured potentials in order to understand the mechanism of SbFE sensor performance.

“…Alternative materials which have the same capability to mercury are bismuth and antimony due to intermetallic compounds of analytes and these materials. Because the bismuth film modified electrode was not suitable for determination of copper(II) and mercury(II) ions , antimony film modified electrode became an attractive material for simultaneous detection of cadmium(II), lead(II), copper(II), and mercury(II). Hocevar and coworkers reported the in‐situ antimony film carbon paste electrode (SbF‐CPE) as an electrochemical sensor.…”

The proposed chemically modified electrode was graphene oxide that was synthesized via Hummer's method followed by reduction of antimony film by in‐situ electrodeposition. The experimental process could be concluded in three main steps: preparation of antimony film, reduction of analyte ions on the electrode surface and stripping step under the conditions of square wave anodic stripping voltammetry (SWASV). A simple and rapid approach was developed for the determination of heavy metals simultaneously based on a sequential injection (SI), an automated flow‐based system, coupled with voltammetric method using antimony‐graphene oxide modified screen‐printed carbon electrode (SbF‐GO‐SPCE). The effects of main parameters involved with graphene oxide, antimony and measurement parameters were also investigated. Using SI‐SWASV under the optimal conditions, the proposed electrode platform has exhibited linear range from 0.1 to 1.5 M. Calculated limits of detection were 0.054, 0.026, 0.060, and 0.066 μM for Cd(II), Pb(II), Cu(II) and Hg(II), respectively. In addition, the optimized method has been successfully applied to determine heavy metals in real water samples with acceptable accuracy of 94.29 – 113.42 % recovery.
