Electrochemical determination of triclosan at a mercury electrode

Hydrotrope-driven disruption of micellar encapsulants for voltammetric detection of triclosan

“…However, these solvents, needed in large excess, resulted in phase separation while dispersing the products containing the active. Ex situ extraction of TCN using hexane has also been reported [18]. In contrast to the aqueous systems, organic solvents pose environmental concerns and hence the use of hydrotropes was resorted to for electroanalytical determination of TCN.…”

“…In contrast to the aqueous systems, organic solvents pose environmental concerns and hence the use of hydrotropes was resorted to for electroanalytical determination of TCN. Hydrotropes are often used to optimise the cloud point of non-ionic and anionic surfactants in alkaline cleaners and increase the aqueous solubility of other organic compounds [18][19][20]. Thinning of the viscous products by addition of hydrotropes happens through loosening of the micellar aggregates.…”

Nanofibrillar Cellulose‐Chitosan Composite Film Electrodes: Competitive Binding of Triclosan, Fe(CN)63−/4−, and SDS Surfactant

“…As a phenol it is readily oxidized and the anodic peak current observed in voltammetric measurements has been employed for the quantitative determination for example at mercury electrodes [35], at carbon microfibers [36], and at screen-printed electrodes [37]. The hydrophobic nature of the triclosan anion has been exploited recently for the accumulation and detection in carbonchitosan thin-film electrodes [38] and in cellulose-PDDAC films [21].…”

Electrochemical reduction of 5-chloro-2-(2,4-dichlorophenoxy)phenol (triclosan) in dimethylformamide

“…Over the past decade, there has been a number of publications [1][2][3][4][5][6][7][8][9][10][11] pertaining to the electrochemical behavior of triclosan. Pemberton and Hart [1] used a screen-printed carbon electrode for the analytical determination of triclosan in toothpastes and mouthwashes; in an aqueous medium at pH 10, electrooxidation of triclosan gives a single wave that involves a one-electron transfer.…”

“…Pemberton and Hart [1] used a screen-printed carbon electrode for the analytical determination of triclosan in toothpastes and mouthwashes; in an aqueous medium at pH 10, electrooxidation of triclosan gives a single wave that involves a one-electron transfer. Safavi et al [2,3] investigated the electrochemical behavior of triclosan at mercury cathodes. Using cyclic voltammetry and controlled-potential electrolysis, Wang and co-workers [4] investigated the direct reduction of triclosan at carbon cathodes in aqueous buffer solutions and in methanol or dimethylformamide containing tetra-n-butylammonium hydroxide; two products, chlorobenzene and 2-phenoxyphenol, were identified.…”
