Voltammetric Determination of Hesperidin on the Electrode Modified with SnO₂ Nanoparticles and Surfactants

Abstract

Highly sensitive voltammetric method for hesperidin determination is developed using glassy carbon electrode modified with SnO 2 nanoparticles (SnO 2 NPs) and surfactants. The highest oxidation currents of hesperidin are observed in the case of cationic 0.50 mM cetylpyridinium bromide (CPB). Parameters of hesperidin electrooxidation have been calculated. Adsorptive anodic differential pulse voltammetry (AdADPV) in phosphate buffer pH 7.0 after 120 s accumulation provides linear dynamic ranges of 0.10-10 and 10-75 μM with the detection limit of 0.077 μM. The selectivity of hesperidin response is proved in the presence of inorganic ions, saccharides, ascorbic acid and other natural phenolics.

Hesperidin: A Review on Extraction Methods, Stability and Biological Activities

“…Besides liquid chromatography, thin layer chromatography [51] capillary electrophoresis [52] and electrochemical methods [53][54][55] were also applied for hesperidin determination in citrus juices and peels. In addition, electroanalytical sensors can also be used in miniaturized form with a high degree of portability.…”

Selective Voltammetric Sensor for the Simultaneous Quantification of Tartrazine and Brilliant Blue FCF

“…MnO 2 nanorods have been used as an electrode surface modifier. Surfactants have been shown as effective dispersing agents for the preparation of metal oxide nanoparticle dispersions [ 28 , 30 , 32 , 33 , 42 ]. Therefore, cationic, anionic, or non-ionic surfactant solutions have been studied as potential dispersing agents for MnO 2 nanorods.…”

“…are promising materials for bio- and electrochemical sensing due to the chemical and electrochemical inertness, large surface area, and biocompatibility [ 25 , 26 ]. In particular, voltammetric sensors based on metal oxide nanoparticles have been developed for the determination of antioxidants [ 27 , 28 , 29 , 30 , 31 , 32 , 33 ], pharmaceuticals [ 34 ] and drugs [ 35 ], and pollutants [ 36 , 37 ]. Few data are available for determining food dyes.…”

Novel Electrodes Based on the Electropolymerized Nanocoatings for the Selective Voltammetric Quantification of Flavanones

“…Homogeneous suspensions of carbon nanomaterials (0.5 mg A limited number of chemically modified electrodes has been developed for the voltammetric quantification of hesperidin and naringin. Carbon nanomaterials [8,9], metal-based nanomaterials [10,11], tin dioxide [12] and silica [13] nanoparticles, amberlite-IRA 400 [14,15], and DNA [16,17], as well as poly-o-aminophenol [18]-and poly-o-aminothiophenol [19]based molecularly imprinted polymers are used as a sensitive layers of modified electrodes.
