摘要：
The kinetics of decomposition of [PVA.Mn(VI)O42-] intermediate complex have been studied spectrophotometrically. A first-order dependence on the intermediate concentration was observed. The decomposition rate was found to be base-catalysed. The kinetic parameters have been evaluated and a mechanism consistent with the results obtained is discussed.
