“…2 Gallium film electrode has been proposed to eliminate copper interference on zinc determination in anodic striping voltammetry. 3 These findings shows that we can take an advantage of gallium and its alloy electrodes as alternative to toxic mercury for trace metal ion analysis in voltammetry. Eutetic gallium indium (EGaIn ) is a another alloy of gallium metal.…”

Adsorption of a series of primarily substituted hydrocarbons (RX; C 18 H 37 PO(OH) 2 (ODPA), C 17 H 35 COOH, C 18 H 37 OH, C 18 H 37 NH 2 and C 18 H 37 SH) onto solid gallium substrates with and without UV/ozone treatment was studied using contact angle goniometry, spectroscopic ellipsometry and cyclic voltammetry (CV). UV/ozone treatment offered a hydrophilic surface hydrogen bond interaction of a phosphonate group with surface oxide. These results will provide a means for controlling the surface properties of oxide-coated gallium that play an essential role in monolayer conductivity measurements and electroanalytical applications.All the results have been published as "Chrishani M

“…It is the inspiration as a driving force that had started the new activities in seeking analogues or alternatives to both BiFEs and BiEs. The result of such endeavors is a new family of metallic film electrodes and related configurations, namely: antimony film-and antimony powder-modified electrodes [201 -212], lead film- [213 -218], tin film- [219], gallium film- [220], cobalt film- [221], or even selenium film- [222] plated electrodes. Although almost all these electrodes mean a step back with respect to the "green-chemistry" concept, they may offer particular advantages in some specific applications.…”

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.

“…When an intermetallic compound is formed, the stripping peaks for the metals of interest may be shifted, distorted and/or depressed [1,5,8]. In the literature, formation of several intermetallic compounds have been addressed; among them, formation of intermetallic Cu-Zn compounds are commonly reported [5][6][7][8][9][10][11][12][13][14][15], especially at a mercury (Hg) [7,[9][10][11][12] and bismuth film electrodes [5,6,13] but also for other electrodes such as a glassy carbon (GC) [14] and in a nanocrystalline diamond thin-film electrodes [8].…”

“…Frequently, to overcome this limitation, the addition of gallium ions (Ga 3 + ) has been suggested [6,9,12] and Tyszczuk et al [15] proposed the application of Ga film electrode for eliminating the Cu interference in the anodic voltammetric determination of Zn. Recently, to overcome this limitation, the application of chemometric tools proved to be an alternative to be considered [5].…”

The simultaneous determination of Zn and Cu by anodic stripping voltammetry (ASV) is prone to errors due to the formation of Cu-Zn intermetallic compounds. The main aim of this work was to study the possibility of simultaneous determination of Zn and Cu, together with Hg and Pb, using a mercury-free solid gold microwire electrode. The multi-element detection was carried out by differential pulse anodic stripping voltammetry (DPASV), in a chloride medium (0.5 M NaCl) under moderate acid conditions (HCl 1.0 mM) in the presence of oxygen, where the gold microwire electrode was used as stationary or vibrating working electrode during the deposition step. Under these conditions, no formation of Cu-Zn intermetallic compounds were found for concentrations usually determined in surface waters. In addition, quantification of Zn and Cu, together with Hg and Pb, can be performed in a wide range of concentrations (about two orders of magnitude) using the same sample, in a very short period of time. The detection limits for Cu, Hg, Pb and Zn, using a vibrating electrode and 30 s of deposition time, were 0.2 mg L À1 for Hg, 0.3 mg L À1 for Pb and 0.4 mg L À1 for Zn and Cu, respectively. The proposed DPASV methods were successfully applied to the determination of Cu, Hg, Pb, and Zn in a certified reference fresh water, river, tap and coastal sea waters. These results proved the applicability and versatility of the proposed methods for the analysis of different water matrices and showed that a gold microwire electrode is a suitable choice to determine simultaneously Zn and Cu.
