“…S. B. Hoceval et al [26] reported the determination of at BiFE using catechol as a complexing agent for Sn (IV) to assist the analyte deposition before the anodic stripping of the deposited metal. And the similar results were obtained when the analysis was carried out in the presence of caffeic acid as a complexing agent for Sn (II) [27]. C. Prior reported that the method of ASV using a BiFE was applied to determining Sn (II) in the presence of cetyltrimethylammonium bromide [28] and trace concentration of Sn (IV) was analyzed with a BiFE by square-wave anodic stripping voltammetry in a supporting electrolyte of 2.5 M sodium bromide [29]., respectively.…”

“…These values were in the trace analytical concentration range. From the results of Table 1, it can be seen that this work has lower detection limit and wide linear range detection of Sn 2+ than the earlier reports [23,[27][28][29]34], or the detection limit reached the same order of magnitude in the previous reports [26,35].…”

“…Several methods have been already developed for the determination of Sn 2+ with its own advantages and limitations. Measurement techniques mainly include spectrophotometry [14], fluorescence [15], atomic absorption spectrometry [16,17], ICP-MS [18], atomic emission spectrometry [19], chemiluminescence [20], GC-MS [21], potentiometry [22], polarography [23], cathodic stripping voltammetry [24,25], and ASV using BiFE [26][27][28][29]. The recent results of determining the tin by ASV using BiFE were summarized as follow.…”

We report on an anodic stripping voltammetric method for the determination of tin using a glassy carbon electrode modified with bismuth and poly(bromophenol blue). After an accumulation time of 60 s at −1.20 V (vs. SCE), the response of the electrode to tin in 1.0 M HCl is linear in the concentration ranges from 20 nM to 1.0 μM, and from 1.0 μM to 20 μM, with a detection limit of 7.0 nM (at an SNR of 3) and with relative standard deviations in the order of 3.0-3.8%. The method was validated by comparing the results with those obtained by AAS and successfully applied to the determination of tin in canned food.

Biodiesel analysis often requires large amounts of chemicals and organic solvents with consequent generation of large waste volumes. However, several environmentally friendly alternatives have been presented for assay of biodiesel quality control parameters. These approaches include direct analysis with reagentless procedures, improved sample preparation by dilution or analyte extraction with nontoxic solvents, preparation of emulsions or microemulsions, and sample mineralisation under mild conditions as well as strategies for minimization of reagent consumption and waste generation. These greener alternatives are critically reviewed, highlighting the advantages and limitations of each approach in biodiesel analysis. Alternative analytical techniques (e.g. flow analysis and electrochemical detection), predictive studies, and measurement of physicochemical parameters are also discussed.

a b s t r a c tMechanism and kinetics of anodic stripping electrode processes of Zn(II), Cd(II) and Pb(II) at bismuth (BiFE) and antimony (SbFE) film as well as bare glassy carbon (GCE) electrodes have been studied with respect to our recent published theoretical considerations developed for square-wave voltammetry (SWV). Mechanistic aspects of electrode reactions have been elucidated by a qualitative comparison of simulated and experimental data for three different electrode reaction mechanisms, i.e. simple anodic stripping mechanism, anodic stripping mechanism coupled with adsorption of metal analyte ions, and mechanism affected by interactions within the particles of the metal deposit on the electrode surface. The electrode kinetics has been estimated by the method of quasireversible maximum and by analyzing the peak potential separation between forward and backward SW components, under variation of the SW amplitude. Electrode mechanisms and kinetics are different at bismuth compared to antimony film electrodes. The electrode reactions of Pb(II) and Cd(II) at BiFE involve adsorption phenomena, while electrode processes of all three analytes are free of adsorption at SbFE. At BiFE, the electron transfer standard rate constants of all three analytes are quite comparable, ranging within the interval from 1 to 3 cm s −1 . At SbFE the electrode kinetics of Cd(II) and Pb(II) are almost the same, while the electrode reaction of Zn(II) is significantly slower. Our results showed that the kinetics of all examined electrode reactions are slower at SbFE as compared to those observed at BiFE.
