Electrochemical oscillation of vanadium ions in anolyte

Recovery and Separation of Vanadium and Chromium by Two-Step Alkaline Leaching Enhanced with an Electric Field and H2O2

“…Vanadium existed in low valence as V­(III) and V­(IV) in the residue, as seen from Figure . During the leaching process, the H 2 O molecule or OH – was oxidized to • OH by the electric field. ,, Then it migrated toward the bulk solution and reacted with the low-valence vanadium in the residue and oxidized it to high-valence vanadium (V­(V)), which highly dissolved in the alkaline medium. The reactions during the leaching process can be expressed by the model shown in Figure and the equations as follows , where MO x stands for the metal electrode.…”

The biosensor based on electrochemical dynamics of fermentation in yeast Saccharomyces cerevisiae

“…Oscillating reactions are also known in electrochemistry, e.g. spontaneous oscillations of electrode potential [8], the Belousov-Zhabotinsky, Bray-Liebhafsky, Briggs-Rauscher reactions [9], [10] or biochemical peroxidase-oxidase and liquid membrane oscillators [8], [11]. The formation of hydronium and carbonate ions H 3 O + , HCO 3 and CO 3 2from carbon dioxide in the aqueous phase can also be considered from the viewpoint of coupled oscillators.…”

Development of Electrochemical Oscillation Method for Identification of Prunus persica, Prunus davidiana, and Prunus armeniaca Nuts

“…At present, the Belousov-Zhabotinsky (B-Z) oscillation reaction is most widely used in analysis and detection, followed by the copper ion oscillation system (Alfifi et al, 2016;Luiz Fernando Oliveira Maia et al, 2019;Nawabi et al, 2019;Ullah et al, 2019). There are also Bray-Liebhafsky oscillation reaction, Briggs-Rauscher oscillation reaction, peroxidaseoxidase biochemical oscillator (peroxidase-oxidase oscillation system), and liquid membrane oscillator (Mukouyama et al, 2016;Bai et al, 2017;Peng et al, 2017;Chan and Dow, 2019;Ding et al, 2019). The basis for applying chemical oscillation reaction to analysis and detection is that the substance to be tested can interfere with the oscillation reaction.…”
