“…Therefore, it can be concluded that the oxidation process of vanillin at FePc MOF/GCE involves two protons and two electrons, which is consistent with previously reported results. [50][51][52] The proposed mechanism for vanillin oxidation is shown in Scheme 2.…”

“…The analytical parameters were given comparatively between the proposed method and some previous studies in Table . The LOD value of the ATT modified Au electrode is lower than those previously reported in the literature . In general, the synthesis of coating substances and its modification of the electrode surfaces are time‐consuming and complicated, whereas the preparation of the ATT‐Au modified electrode is quick and simple.…”

Electrochemical oxidation of vanillin (VAN) in the presence of caffeine (CAF) was studied on a gold (Au) electrode modified with 3‐amino‐1,2,4‐triazole‐5‐thiol (ATT) film by using differential pulse voltammetry (DPV) and cyclic voltammetry (CV) method. The formation of the ATT film on the Au electrode surface was characterized by the CV, fourier transform infrared spectroscopy (FTIR) and impedance spectroscopy (EIS) methods. A single irreversible oxidation peak of the VAN was obtained by using the CV method. The determination of VAN in the presence of CAF was carried out at pH 4 in Britton Robinson buffer (BR) by the DPV method. Under the optimal conditions, the oxidation peak current was proportional to the concentration of VAN in the range of 1.1 μM to 76.4 μM in the presence of CAF with the correlation coefficient of 0.997 and the detection limit of 0.19 μM (S/N=3). The selective determination of VAN in a commercial coffee sample was carried out with satisfactory results on the ATT‐Au modified electrode.

“…Electrochemical sensors are gaining great importance because of their fast response, high sensitivity, cheap instrumentation, online detection ability, etc. (Minematsu et al., 2013; Silva et al., 2015; Veeramani et al., 2015; Vilian et al., 2016; Wang et al., 2015; Wu et al., 2016; Xinying, 2014; Zheng et al., 2010). Recently, different electrochemical sensors were reported for determination of vanillin (Ali et al., 2017; Alpar et al., 2018; Cheraghi et al., 2017; Deng et al., 2015; Jiang et al., 2014; Raril & Manjunatha, 2020; Shang et al., 2014; Shen et al., 2014; Tabanlıgil Calam, 2020; Tian et al., 2020; Yardim et al., 2013).…”

A simple and cost‐effective electrochemical sensor was developed for the determination of very low amounts of vanillin in various foodstuffs. Multi‐walled carbon nanotubes (MWCNTs) modified glassy carbon electrode (GCE) beside differential pulse voltammetry (DPV) was applied for the measurement of vanillin. The effect of several variables on the voltammetric sensing of the vanillin, such as pH, buffer type and concentration, and the amount of MWCNTs were investigated. Using the optimized condition, the proposed sensor can detect vanillin in the concentration range from 4.15 to 294.12 µM with a correlation coefficient of 0.999, while the limit of detection is calculated to be 3.44 µM. Furthermore, to improve the detection sensitivity and detection of sub‐micromolar levels of vanillin, the capability of the Adsorptive stripping differential pulse voltammetry (AdSDPV) technique was also studied. The detection limit improved to 8.51 nM using the stripping method. The developed sensor was successfully utilized for the determination of vanillin in some food samples such as ice cream and cake with desirable accuracy and recovery. Due to its simplicity and ability to detection of trace amounts, the proposed sensor can be easily used in quality control labs and industry tests to measure vanillin. Novelty impact statement Despite various methods reported on measuring vanillin, the proposed electrochemical sensor is very simple, cost‐effective, and fast. This method can measure vanillin in a wide variety of foodstuffs with a lower limit of detection and is less prone to interferences from other possible compounds. Because of its simplicity and ability to detect trace amounts (nano‐molar LOD), the proposed sensor has the capability of using in quality control laboratories and industrial tests for measuring vanillin.
