Mikheeva, L. Anisimova] The conditions are found for the voltammetric determination of fat-soluble vitamin E (α-tocopherol acetate) in nonaqueous media using carbon electrodes of different types. The electrochemical behavior of vitamin E is studied, and some parameters of the electrode reaction that are of analytical importance are estimated. The stage of sample preparation is optimized by the multifactorial design of experiments. Procedures for determining vitamin E in multicomponent vitaminized mixtures by differential voltammetry are developed and metrologically certified. Pleiades Publishing, Ltd., 2007 Mikheeva E.
