“…However, the applicability of carbon materials in the simultaneous determination of a mixture of organic compounds is limited due to the overlapping of peaks caused by the proximity of the oxidation potentials . In this sense, surfactants can be used as a strategy for improving the electrochemical performance, since it helps to solubilize organic compounds and also provides specific orientation of the molecules at the electrode interface, which heavily influences the electrochemical process of electroactive species . Furthermore, surfactants stabilize the electrochemical signal, enhancing the electron transfer rate and improving the detection limits .…”

In this work, a simple and low‐cost method was developed for the simultaneous determination of the antioxidants tert‐butylhydroquinone (TBHQ) and butylated hydroxyanisole (BHA) in the presence of the cationic surfactant CPB by square wave voltammetry (SWV) technique using a carbon black paste electrode (CBPE). The performance of the method was investigated by varying parameters such as pH, electrolyte, and type and concentration of surfactant. Under the optimum conditions of 0.2 mol L−1 phosphate buffer (pH 7.0), 600.0 μmol L−1 of cetylpyridinium bromide surfactant and SWV operating parameters optimized through the Doehlert matrix, the method presented low limits of quantification for TBHQ and BHA (0.23 and 0.26 μmol L−1, respectively) and high precision in successive measurements. The proposed method was applied in mayonnaise, margarine and biodiesel and the accuracy of method was checked by the HPLC technique.

“…The effect of surfactants on the electrochemical process of analytes on BDDEs has been fruitfully explored along with electrochemical pretreatments, mostly by Yardim and collaborators, [234,240,243,265,[271][272][273][274][275][276] but also by others. [200,[277][278][279] Yardim et al [271] reported that the use of surfactants significantly enhanced the voltammetric response of an APT-BDDE (+ 1.30 V vs. Ag/AgCl (3 mol L À 1 NaCl)/30 s) for the polycyclic aromatic hydrocarbon benzo[a]pyrene; using SW-AdASV and the anionic surfactant sodium dodecylsulfate (SDS), this analyte was determined in the concentration range of 0.016-200 nmol L À 1 (LOD = 2.86 nmol L À 1 ) in a Britton-Robinson buffer, pH 2.0 con- APT or CPT conditions: + 0.5 A cm À 2 /30 s or À 0.5 A cm À 2 /120 s, in 0.5 mol L À 1 H 2 SO 4 .…”

Analytical Applications of Electrochemically Pretreated Boron‐Doped Diamond Electrodes

et al. 2020

The several outstanding properties of boron‐doped diamond electrodes (BDDEs) have allowed their application for various purposes, among them electrochemical sensing. However, the electrochemical response of many redox species on BDDEs can be strongly dependent on whether their surfaces are predominantly hydrogen‐ (HT) or oxygen‐terminated (OT). Fortuitously, electrochemical pretreatments themselves can be used to enrich in situ the BDEE surface in one or the other type of termination. The surface of a cathodically pretreated BBDE (CPT‐BDDE) becomes enriched in HTs, whereas that of an anodically pretreated BDDE (APT‐BDEE) becomes enriched in OTs. Thus, when suitable, the electrochemical activity of a BDDE for a given analyte may be tuned by electrochemical pretreatments, yielding enhanced sensing properties. The main purpose of this review is the compilation and discussion of papers published after 2009 reporting on electroanalytical applications based on a CPT‐BDDE or an APT‐BDDE. Procedures to perform proper electrochemical pretreatments are also discussed.

“…Ambroxol (AMB), a potential antioxidant drug belonging to the expectorant class, was quantified by square‐wave adsorptive stripping voltammetry methodology proposed by Levent and coauthors . The authors used phosphate buffer pH 2.5 containing 4×10 −4 mol L −1 sodium dodecylsulfate at 1.02 V (vs. Ag/AgCl/KCl sat ) (after 30 s at 0.50 V) on BDD electrodes.…”

Electroanalysis of Pharmaceuticals on Boron‐Doped Diamond Electrodes: A Review

diamond (BDD) electrodes possess outstanding physical, chemical, and electronic properties and have been successfully, yet in a limited way, explored in the electroanalysis of substances with therapeutic action (analgesics, antipyretics, antibiotics, anti-inflammatories, antihypertensives, antidepressants, vitamins, and others) in diverse milieus (pharmaceutical formulations, urine, serum, whole blood, surface waters, seawaters, groundwater, wastewaters, etc.). Therefore, in this Review, a broad overview of the available scientific information on recent progress and achievements of the application of bare or modified BDD electrodes to the bioanalytical and environmental detection of pharmaceutical compounds is presented. The main parameters, for example boron concentration, applied operational conditions during pretreatment, chemical and physical structure, and other influential factors on the electroanalytical BDD electrodes performance, are discussed.[a] Dr.
