Voltammetric monitoring of electrochemical reduction of riboflavin using silver solid amalgam electrodes

Electrochemical sensor based on bismuth-film electrode for voltammetric studies on vitamin B2 (riboflavin)

“…Page 17 of 40 A c c e p t e d M a n u s c r i p t 17 A comparison between the responses obtained using the BiFE-SWAdSV procedure and published data [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] indicates that the BiFE is suitable for the electroanalysis of samples to determine the vitamin B 2 concentration. However, a large diversity of sensors was used to obtain the linear ranges and detection limits used for comparison.…”

Sensitive voltammetric determination of herbicide terbutryn using solid electrodes based on silver amalgam and boron-doped diamond

“…AgSAE represents the step between mercury and solid electrodes, and it combines the advantages of the both above-mentioned types, especially the hydrogen evolution at highly negative potential and good possibility of surface regeneration comparable with HMDE, with the good mechanical stability and nontoxic electrode material of solid electrodes [20]. The AgSAE was used up to now for many various analytical applications in determination of inorganic and organic compounds, as well as in the analysis of peptides and DNA [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Various pesticides were already analyzed with different types of amalgam electrodes [35][36][37][38][39][40][41].…”

Simple, Rapid and Selective Chronopotentiometric Method for the Determination of Riboflavin in Pharmaceutical Preparations Using a Glassy Carbon Electrode

“…The coenzymes participate in a range of redox reactions in intermediary metabolism by accepting and donating two electrons in the isoalloxazine ring. 1 These reactions are substantial for tissue respiration, normal cellular function, growth, and development. Although riboflavin is found distributed in virtually all naturally occurring foods, especially rich sources of this vitamin are milk and dairy products, meat, eggs, livers, cereals and fresh leafy vegetables.…”

“…Although riboflavin is found distributed in virtually all naturally occurring foods, especially rich sources of this vitamin are milk and dairy products, meat, eggs, livers, cereals and fresh leafy vegetables. [1][2][3] Regular daily intake of riboflavin is important because it is not stored in human body in appreciable amounts. Though no pathologically severe symptoms attributed to vitamin B 2 deficiency have been observed in humans, diets lacking the vitamin caused lesions of the muco-cutaneous surfaces and intense photophobia.…”

“…18,19 Among electrochemical methods, those based on voltammetry and voltammetric stripping analysis are mostly used for riboflavin assays. 1,[18][19][20][21][22] Various types of electrodes were considered in analysis of riboflavin, including mercury electrodes, 22,23 gold electrode, 18 different types of carbon paste electrode, 2,22,24 glassy carbon electrodes, 25,26 and bismuth based electrodes. 27,28 Most of the mentioned electrodes are complicated to prepare, often with low reproducibility of fabrication.…”
