“…The images clearly depict the formation of bismuth microcrystals aggregated in rosettes indicating that these microcrystals are formed on the surface of the gold electrode instead of a bulk deposit. These results are similar to those obtained with a deposition from an acidic solution using carbon substrate [38,39]. Note that the structure of the tartrate crystals is still detectable in Figures 1 C and 1 D, although with a lower contrast.…”

“…In both cases a LOD of 40 ng L À1 was achieved which is the lowest value compared with other electroanalytical methods reported in the literature [15][16][17][18][19]. This sensitivity, attributed also to a 10-electron transfer process [39], is associated with excellent repeatability with relative standard deviation (RSD) of 2.2 % based on 20 consecutive measurements of 0.5 mg L À1 Ni(II).…”

Simultaneous Adsorptive Cathodic Stripping Voltammetric Determination of Nickel(II) and Cobalt(II) at an In Situ Bismuth‐Modified Gold Electrode

A study on the simultaneous determination of Ni(II) and Co(II) dimethylglyoximates (Ni-DMG and Co-DMG) through adsorptive cathodic stripping voltammetry at an in situ bismuth-modified gold electrode (Bi-AuE) is reported. The key operational parameters, such as Bi(III) concentration, accumulation potential and accumulation time were optimized and the morphology of the Bi-microcrystals deposited on the Au-electrode was studied. The BiAuE allowed convenient analysis of trace concentrations of solely Ni(II) or of Ni(II) and Co(II) together, with cathodic stripping voltammograms characterized by well-separated stripping peaks. The calculated limit of detection (LOD) was 40 ng L À1 for Ni(II) alone, whereas the LOD was 98 ng L À1 for Ni(II) and 58 ng L À1 for Co(II), when both metal ions were measured together. The optimized method was finally applied to the analysis of certified spring water (NIST1640a) and of natural water sampled in the Lagoon of Venice. The results obtained with the BiAuE were in satisfactory agreement with the certified values and with those provided by complementary techniques, i.e., ICP-OES and ICP-MS.

“…Bismuth is used for the modification of different kinds of carbon based electrodes such as carbon paste electrodes, 6,9-11 carbon fiber electrodes, 8 graphite epoxy composite electrodes, 12,13 carbon nanotube nanoelectrode array, 14 carbon film electrodes, 15,16 boron doped diamond 17 and particularly glassy carbon electrodes. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] It is also used for modification of other types of electrode materials such as screen printed electrodes, 36,37 copper disk electrodes, [38][39][40] pencil lead(II) electrode 41 and electrically heated electrode 42 and they are used for detection of different heavy metal ions such as cadmium, 12,14,21,24,26 lead, 12,21,27,29 zinc, 20,26,27 nickel, 23,28,…”

Electroanalytical Determination of Cadmium(II) and Lead(II) Using an in-situ Bismuth Film Modified Edge Plane Pyrolytic Graphite Electrode

et al. 2007

View full text Add to dashboard Cite

A highly sensitive and simple electroanalytical methodology is presented using an in-situ bismuth film modified edge plane pyrolytic graphite electrode (BiF-EPPGE) which is exemplified with the simultaneous determination of cadmium(II) and lead(II). Square-wave anodic stripping voltammetry is utilised with the effects of several experimental variables studied. Simultaneous additions of cadmium(II) and lead(II) were investigated where two linear ranges between 0.1 -100 and 0.1 -300 μg/L and also detection limits of 0.062 and 0.084 μg/L were obtained, respectively. The method was then successfully applied to the simultaneous determination of cadmium(II) and lead(II) in spiked river water, where recoveries of 100.5 and 98% were obtained, respectively. This electroanalytical protocol using edge plane pyrolytic graphite electrodes is one of the simplest methodologies to date using non-mercury based electrodes and is simpler and cheaper than alternatives such as carbon nanotube electrode arrays, suggesting the use of edge plane pyrolytic graphite electrode for routine sensing.

“…In a collection of sixteen publications, one could find very diverse contributions -from optimizations and validations of newly developed methods for trace metal analysis [33 -35, 44, 45], up to the first real-life application of a BiFE in biological/clinical analysis [43]. In addition, further contributions included the first successful attempts to detect selected organic compounds in a FIA arrangement [32], the combination of electrochemical procedures with (ultra)sonication [40,41], the first systematic studies on morphology of bismuth microlayers [37], and proposals of alternate electrode substrates for bismuth films [36,42] or further types of bismuth-based electrodes [46] (including the configuration from compact metal, the so-called "bismuth bulk electrode", BiBE [31]). …”

A Decade with Bismuth‐Based Electrodes in Electroanalysis

et al. 2010

In this article, the decade of electroanalysis with bismuth-based electrodes is reviewed (with 222 refs.). Emphasis is put on the environmentally friendly ("green") character of bismuth electrodes, their versatility and variability in use, as well as the actual classification of the individual types of electrodes, sensors, and detectors that utilize the unique properties of metallic bismuth. Of particular interest is the genesis of the field, when the respective activities and achievements are monitored year by year over the whole period of 2000 -2009, including the circumstances of the introduction of bismuth-coated electrodes into electrochemical stripping analysis. The review highlights all the significant milestones and break-points that had directed the experimental work around the globe, outlining the present days position of this lively, inspiring, and still highly prospective area. Finally, it provides a special insight into electroanalysis with bismuth electrodes through numerous surveys, summaries, and detailed statistical data obtained by analyzing the accessible literature database.
