Abstract

It was shown that tocoferol acetate can be preconcentrated on a nickel acetyl acetonate layer grafted onto the chromatone HMDS in the presence of other organic molecules. Optimum conditions were found for preconcentration and the next desorption. Results of determining vitamin E in polyvitamin preparations are reported.
