“…A plethora of intriguing studies has been conducted in relation to the kinetics of charge transfer processes at liquid/liquid interfaces [18][19][20][21][22][23], electrochemistry of immobilized proteins [24,25], and catalytic mechanisms [26][27][28], revealing that SWV is highly suited for both mechanistic and kinetic characterization of electrode reactions, besides its excellent analytical performances [29][30][31][32][33][34] and its appropriateness for bioanalytical applications [35][36][37][38][39][40][41].…”

The kinetics of surface confined electrode reactions of alizarin, vitamin B12, and vitamin K2 is measured with square‐wave voltammetry over a wide pH interval, by applying the recent methodology for kinetic analysis at a constant scan rate [V. Mirceski, D. Guziejewski, K. Lisichkov, Electrochim. Acta 2013, 114, 667–673]. The reliability and the simplicity of the recent methodology is confirmed. The methodology requires analysis of the peak potential separation of the forward and backward component of the response as a function of the pulse height (SW amplitude), for a given frequency (i.e. constant scan rate) of the potential modulation.

“…As can be seen in Table 2, in order to obtain satisfying results it is necessary to control the pH of the supporting electrolyte with very high precision. The signals recorded using amalgam film electrodes originated from the reduction of the nitro [74][75][76][77][78], keto [79], azo [80], chinone [81], pyrimidine [72], pteridine [72], adenine [82] groups or hydrogen evolution catalyzed by organic compounds adsorbed at the surface of the electrode [73,[83][84][85][86]. Although the reduction of the above-listed organic compounds occurs in more than one step, in most cases only one peak was considered useful for analytical purposes.…”

The success of a voltammetric sensing procedure depends mainly on the proper choice of the working electrode. This is because its ability to accumulate the analyte determines the sensitivity of the method. The main criterion of the selection of the proper working electrode is the available potential window. A variety of conductive materials have been used for the preparation of working electrodes. Of these, two kinds of mercury electrodes-hanging mercury drop and film-were used because of their excellent voltammetric performance and, in particular, their high overpotential of hydrogen reduction. The significant drawbacks of mercury electrodes, however, are the toxicity of the material and the instability of liquid mercury films. To overcome these disadvantages, less toxic mercury-containing materials have been used, such as amalgams and amalgam film electrodes. This group includes renewable silver amalgam film electrodes used for electrochemical stripping sensing purposes. These electrodes have successfully been applied for anodic, adsorptive, cathodic, catalytic voltammetric, and potentiometric stripping determination of trace amounts of inorganic cations and organic compounds in various natural matrices. In this review, the electrode design, characteristics, and application of two kinds of renewable silver amalgam film electrodes are discussed in detail.

“…More direct approach using silver amalgam based electrodes is also a recurring theme in the contemporary literature [18][19][20][21][22], all the works use a mercury film modified AgSAE for some reason, which uses small amounts of mercury for film renewal, but the mercury has to be in a toxic water soluble form, the film is much less stable than a meniscus and the electrode needs to be polished much more often, which is time consuming. Some works focus on the determination of herbicides at classical mercury electrodes [23] this method utilizes the excellent reproducibility of a hanging mercury drop electrode (HMDE) to deconvolute the signals of three herbicides to determine them in a mixture.…”

Abstract:A method for the determination of pesticide Aclonifen (AC) in drinking and river water by differential pulse voltammetry (DPV) on a meniscus modified silver solid amalgam electrode (m-AgSAE) using solid phase extraction (SPE) as a cleanup and preconcentration procedure is described. The limit of detection (LOD) for direct DPV determination of AC in deionized water is 2.7·10 -8 mol·dm -3. LOD for DPV determination of AC in tap water after SPE is 1.6·10 -10 mol·dm -3, the recovery being 55%. LOD for the determination of AC in Vltava river water is 1.9·10 -9 mol·dm -3, the recovery being 65%. Humic acids interfere with the determination in river water; this problem can be resolved by adjusting the pH of the extracted sample to 6. The advantages of this approach are high sensitivity, low LOD, quick and easy sample preparation and fast determination.
