Cyclic voltammetry: a tool to quantify 2,4,6-trichloroanisole in aqueous sample...
Peres, António M.; Freitas, Patrícia; Dias, Luís G.; Sousa, Mara E. B. C.; Castro, Luís M.; Veloso, Ana C. A.Chloroanisoles, namely 2,4,6-trichloroanisole, are pointed out as the primary responsible of the development of musty off-flavours in bottled wine, due to their migration from cork stoppers, which results in huge economical losses for wine industry. A prevention step is the detection of these compounds in cork planks before stoppers are produced. Mass spectrometry gas chromatography is the reference method used...
Determination of 2,4,6-trichloroanisole by cyclic voltammetry
Freitas, Patrícia; Dias, L.G.; Peres, António M.; Castro, Luís M.; Veloso, Ana C.A.The electrochemical reduction of 2,4,6-trichloroanisole (TCA), a chlorinated arene with electron-donating substituents, was evaluated by cyclic voltammetry (CV). TCA is a major concern for the winery industry since it is related with “cork taint”, a wine defect. The results obtained showed that CV could be used to detect and quantify TCA in standard solutions. Linear relationships could be set between the curre...
