Abstract
The mechanisms of reactions between OH, SO4-. and VK3 in aqueous solution h ave been investigated by using pulse radiolytical dynamic absorption spectr oscopy. While VK3 reacts with (OH)-O-. and SO4(-.) respectively, the format ion of dehydrogenated radical of VK3 with characteristic absorption peak ro und 400 nm has been observed, this is also confirmed by the results of lase r photolysis of VK3 in aqueous solution.
