摘要：

It was found that vitamin E reacts with electrogenerated chlorine and bromine, as well as with silver (I) and vanadium(V) in the ratio 1:1 to form alpha-tocopherylquinone. Vitamin A reacts with electrogenerated halogens in the ratio 1:3. Individual fat-soluble antioxidants were determined in model solutions at the milligrain level with RSD between 1 and 4%. The bromine-scavenging antioxidant capacity of some vegetable oils and animal fats was evaluated.
