Abstract

Bivalent manganese in oxidized to the tervalent state in 4.0–5.3 pH (acetate buffers) when treated with an excess of peroxodiphosphate (PDP). Kinetic evidence for the formation of a 1∶1 complex between manganese(II) and PDP was obtained. The reaction exhibits first order dependence on [Mn(II)] and fractional order dependence on [PDP]. The reaction is markedly inhibited by H+ ions. A plausible mechanism consistent with the observed data is proposed.

Abstract

Двухвалентный марганец окисляется до трехвалентного состояния в ацетатных буферах с pH=4,0–5,3 при обработке избытком пероксодифосфата (ПДФ). Получены кинетические доказательства образования комплекса между марганцем (II) и ПДФ с составом 1∶1. Реакция имеет первый порядок по [Mn(II)] и дольный порядок по [ПДФ]. Ионы H+ значительно ингибируют реакцию. Предложен механизм, согласующийся с экспериментальными данными.
