Feasibility of a Nano‐Carbon Black Paste Electrode for Simultaneous Voltammetric Determination of Antioxidants in Food Samples and Biodiesel in the Presence of Surfactant

et al. 2020

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.

A Sensitive Sensor Based on CuTSPc and Reduced Graphene Oxide for Simultaneous Determination of the BHA and TBHQ Antioxidants in Biodiesel Samples

et al. 2016

A novel and sensitive electrochemical sensor was developed for the simultaneous determination of the butylated hydroxyanisole (BHA) and tert‐butylhydroquinone (TBHQ) antioxidants in biodiesel samples employing the differential pulse voltammetry (DPV). In this sense, a glassy carbon electrode (GCE) modified with copper (II) tetrasulfonated phthatocyanine immobilized on reduced graphene oxide (CuTSPc/rGO) allowed the detection of BHA and TBHQ at potentials lower than those observed at unmodified electrodes. The sensor was characterized by cyclic voltammetry (CV) and linear scan voltammetry (LSV). After optimization of the experimental parameters, the analytical curves for simultaneous determination of BHA and TBHQ by DPV technique demonstrated an excellent linear response from 0.1 to 500 µmol L−1 with detection limit of 0.045 µmol L−1 for TBHQ and 0.036 µmol L−1 for BHA. Finally, the proposed method was successfully applied in the simultaneous determination of BHA and TBHQ in six biodiesel samples, and the results obtained were found to be similar to those obtained using the HPLC method with agreement at 95 % confidence level.

“…In this sense, a number of materials have been proposed to development of sensors for antioxidants determination, such as enzymes [6], redox proteins [7], semiconducting nanoparticles [8], graphene [9], metal nanoparticles [10], DNA-modified electrodes [11], and photoactive nanomaterials [12]. Thus, sensors based on various signal transduction principles have been used for the determination of antioxidants including electrochemical [6][7][8][9], colorimetric [13], optical [14], and photoelectrochemical [15].…”
