摘要：

The kinetics of the permanganate-sulfite redox reaction has been studied in the alkaline medium using a stopped-flow technique. In the pH range 10 to 12 the reaction was found to obey the rate expression: -1/2d[MnO4-]/dt = (k1 + k2[OH-]) [MnO4-] [SO32-]. Mechanisms for the two paths involving the formation of a (O3MnOSO3)3- complex prior to the rate-determining step are consistent with the data.
