摘要：

The kinetics and mechanism of the oxidation of sulfite to sulfate by tris(pyridine-2-carboxylato)manganese(ni) in Na(pic)-picH (where, Na(pic) = sodium salt of picolinic acid, picH = picolinic acid) buffer has been studied in the pH range 5.22-6.10. The rate of the reaction Increases with increasing [substrate] but with decreasing acidity. A mechanism consistent with experimental observation has been proposed and the activation parameters for the rate-determining step evaluated.
