Determination of biologically active acids based on the electrochemical reduction of quinone in acetonitrile+water mixed solvent

A Unified Ion Chromatographic System for the Determination of Acidity and Alkalinity

“…[5][6][7] The detection levels achieved with these methods were comparable to, or even better than, those obtained using multipoint titration. However, these techniques were generally less accurate.…”

Direct evidence of hydrogen-bonding and/or protonation effect on p-benzoquinone electrochemical reduction by in situ IR spectroelectrochemical study

“…Addition of H 2 O to CH 3 CN solutions results in positive shifts of both BQ's reduction steps [19,43]. Representative cyclic voltammograms are shown in Fig.…”

“…In organic-water mixed media, two well-separated reduction waves also are observed at low concentrations of water [19,20]. With increasing concentrations of H 2 O, the positive shift of both redox wave is found and the wave at more negative potentials shift more strongly than the positive one, and finally the two redox waves overlap in high concentrations of H 2 O.…”

“…p-benzoquinone is the simplest quinone and has been studied extensively. Indeed the electron transfer of benzoquinone in aprotic media [13][14][15][16][17][18], organic-water mixed media [19,20], wellbuffered aqueous solution [1,[21][22][23][24][25][26][27], and unbuffered aqueous [23][24][25][26][27][28][29][30][31][32][33][34] solution has been studied through modern electroanalytical techniques from polarography, rapid-scan voltammetry, to spectroelectrochemistry [15][16][17][18]23,26,27].…”

Quantification of histamine in various fish samples using square wave stripping voltammetric method

“…Despite the use of electroanalytical methods for the determination of biogenic amine in general (Łuczak and Bełtowska-Brzezinska 2013;Di Fusco et al 2011;AlonsoLomillo et al 2010;Chang et al 2012;Muresan et al 2008;Kuklinski et al 2010), only a few studies are available for the voltammetric determination of histamine (Akbari-Adergani et al 2010Kim et al 2001) and, as far as we know, no work dealing with indirect determination of histamine.…”
