Ziyatdinova, G. Determination of sterically hindered phenols and α-tocopherol by cyclic voltammetry / G. Ziyatdinova, A. Khuzina, H. Budnikov // Anal. Lett. - 2012. - V. 45. - No. 12. - P. 1670-1685. |
| Аннотация |
Sterically hindered phenols (2,6-di-tert-butyl-4-methylphenol (BHT) and its derivatives) are irreversibly oxidized at þ0.96?1.30V on glassy carbon electrode (GCE) in 0.1M LiCIO4 in acetonitrile in accordance to cyclic voltammetry data. a-Tocopherol gives oxidation step at þ0.4V on voltammograms under the same conditions. Oxidation process leads to formation of corresponding quinoid derivatives. Calibration graphs linearity is 1.5?2 order for all compounds under investigation. Limits of detection are in the range 9.6?44.3 lM. The approach has been applied for determination of BHT and a-tocopherol in vegetable and lubricating oils as well as pharmaceuticals and cosmetics using preliminary single extraction of analytes with acetonitrile for 15 min at oil/extractant ratio of 1:2.5. |
