“…The idea of this work was to determine bentazone at unmodified boron-doped diamond electrode, as a relatively new electrode material with favorable characteristics. Nowadays, boron doped diamond electrode is widely investigated unmodified ("green") electrochemical sensor, exhibiting numerous advantages such as negligible adsorption phenomenon, very low background current and one of the widest linear ranges, requires no additional reagent costs and manipulation steps to increase determination characteristics of some different groups of compounds [14][15][16][17][18][19]. BDDE is quite resistant to surface contamination and poisoning which was a limiting factor for previous determination of this compound on bare glassy carbon electrode [20].…”

“…The stock solution (1 mM) was prepared in freshly distillated methanol. All electrochemical studies of bentazone were done in Britton-Robinson (BR) buffer solutions [16]. Ultra pure water (18 MΩ cm) obtained from Millipore Simplicity 185 and analytical reagent grade chemicals were used throughout the experiments.…”

“…Trifluoperazine (TFP), a phenothiazine derivative with potent physiological activity, was quantified by Stankovic and coauthors using DPV methodology . The authors used BR buffer solution at pH 6 on BDD electrodes (doping level of 1000 ppm) to quantify two oxidation peaks on higher potentials of TFP.…”

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.

“…The main part of each electrochemical experiment is the working electrode used for the reduction or oxidation of the target compound. Some general electrodes including glassy carbon, [1–5] gold, [6,7] platinum, [8–10] boron‐doped diamond [11,12] and carbon paste [13–16] have been currently applied in this regard. Also, modification of these electrodes with various organic, inorganic and biological modifiers has also extended the applicability of these electrodes [17,18] .…”

Herein, a new copper/mercury‐based amalgam electrode with 45 wt % copper was introduced. An amalgam electrode with the lowest mercury content among all amalgam electrodes, reported so far,was introduced. The method of making and activating the electrode was investigated and the working conditions were established. The as‐prepared electrode was employed to determine azathioprine(Aza) using differential pulse adsorptive stripping voltammetry (DPASV) method. The required factors were considered for the electrode voltammetric response to evaluate and optimize Aza level. The proper response of this electrode was obtained in Brinton‐Robinson buffer(BRB) (pH 2) at −0.15 V for 200 seconds. The electrode response to the target compound was linear in the concentration range from 0.04 to 1.0 μM. The detection limit was found to be about 1.6×10−8 M. The relative standard deviation (RSD) for 5 determinations was obtained to be about 3.5 % (the average of RSDs calculated for all concentrations, represented in the calibration curve). The method was successfully applied for Aza determination in plasma and urine samples which led to satisfactory results. It can be concluded that the presence of high levels of potential interfering agents such as ascorbic acid and cysteine did not affect the Aza determination.
