摘要：

The kinetics of the oxidation of glutathione by diaquatetrakis(2,2'-bipyridine)-mu-oxo diruthenium(III) ion in aqueous HClO4 have been investigated. The reaction obeys the empirical rate law: - 2d[oxidant]/dt = k[oxidant] [reductant]/[H+] where k = 7.42 +/- 0.40 x 10(-3) s-1 at 25.5-degrees-C, [H+]= 0.005-0.05 M and I = 1.0 M (LiClO4). Free radicals are important in the reaction and a mechanism consistent with the experimental results has been postulated.
