Redox cycling of Mn(II/III) in the presence of (1-)ON(NO)SO3(1-) in the absence and presence of oxygen was studied by following the increase and decrease of Mn(III) spectrophotometrically as a function of , , and pH.The autoxidation reaction exhibits typical autocatalytic behaviour in which the induction period depends on the concentrations of M(III) and (1-)ON(NO)SO3(1-).Under acidic conditions the reaction does not take place in the absence of Mn(III) or O2.The concentrations of O2, Mn(II) and (1-)ON(NO)SO3(1-) determine whether only oxidation of Mn(II) to Mn(III), or reduction of Mn(III) to Mn(II), or both in one or two redox cycles is observed.Preliminary simulations of some of the observed kinetic traces are presented.
