Abstract: The mechanisms of reactions between OH, SO4-· and VK3 in aqueous solution have been investigated by using pulse radiolytical dynamic absorption spectroscopy. While VK3 reacts with ·OHand SO4-· respectively, the formation of dehydrogenated radical of VK3 with characteristic absorption peak round 400 nm has been observed, this is also confirmed by the results of laser photolysis of VK3 in aqueous solution.

Key words: Vitamin K3, Hydroxyl radical, Persulfate anion radical, Oxidation reaction
