“…One of the last is method proposed by our team based on the renovation and activation of the receptor part of the electrode in an additional internal cell placed above the supporting electrolyte. 8 The effectiveness of this solution has been demonstrated for the silver 15 and bismuth electrodes, 16 used in trace analysis of selenium and palladium, respectively. During the previously research, it was also found that the bismuth bulk annular band electrode (BiABE) can be effectively regenerated by in situ method at the presence of the tested solution, in trace analysis of molybdenum, 17 iron 18 and clothianidin.…”

This paper presents the report on preparation and application of the Metallic Annular Band Electrode (MeABE) for differential pulse voltammetric (DPV) determination of riboflavin (vitamin B 2 ). For the construction of electrodes, the bare metallic bismuth, silver and gold were used. The electrochemical behavior of riboflavin on MeABE has been investigated by cyclic voltammetry (CV). The acetate buffer (pH 4.5) was used as the most favorable supporting electrolyte. Under optimal conditions, the peak current was proportional to the concentration of riboflavin in the range; 10-337, 20-249, 10-298 μg L −1 , and detection limits were; 2.4, 5.2, 2.8 μg L −1 for BiABE, AgABE and AuABE, respectively. In case of BiABE the presented results were obtained with accumulation time of 30 s. The proposed electrodes were successfully applied for determination of riboflavin in pharmaceutical samples and optimized voltammetric procedure was validated by studying the recovery of analyte.

“…It is obvious that mercury is the best electrode material in analytical practice. Nevertheless, nowadays, there is a tendency to substitute liquid mercury with other less- or non-toxic electrode material, i.e., bismuth-based [ 18 , 19 ] or amalgam-based electrodes [ 20 – 26 ]. The problem of reducing the amount of mercury used in analytical procedures can be solved with the help of a renewable silver amalgam film electrode (Hg(Ag)FE) [ 23 , 24 ].…”

Electrochemical determination of closantel in the commercial formulation by square-wave adsorptive stripping voltammetry

et al. 2016

In this paper, the square-wave adsorptive stripping voltammetric (SWAdSV) determination of the veterinary drug closantel using a renewable silver amalgam film electrode (Hg(Ag)FE) is presented. As observed in SWAdSV, closantel provided one well-shaped reduction peak suitable for analytical purposes at potential ca. −1.4 V in the Britton–Robinson (B-R) buffer at pH 7.0. At optimal conditions, the SWAdSV response of Hg(Ag)FE for determining closantel was linear over two concentration ranges of 5.0 × 10−8 to 2.0 × 10−7 mol dm−3 and 2.0 × 10−7 to 1.2 × 10−6 mol dm−3 with a detection limit of 1.1 × 10−8 mol dm−3. In addition, a relevance of the developed SWAdSV method was successfully verified by the quantitative analysis of closantel in the commercial formulation Closamectin Pour-On with satisfactory results (RSD = 5.8%, recovery = 101.8%). The results showed that the developed procedure can be adequate for screening purposes. Also, the electrochemical behavior of closantel was characterized by cyclic voltammetry, and it was found that closantel exhibited a quasi-reversible behavior with cathodic peak on the forward scan at ca. −1.4 V and anodic peak on the reverse scan at ca. −1.35 V vs. Ag/AgCl in B–R buffer, pH 7.0. As the obtained results showed that the electrode mechanism of closantel is controlled by the adsorption, the effect of adsorption was studied using the electrochemical impedance spectroscopy technique.Graphical abstract
