The calculated high amplitude oscillations and kinetic phase diagram are in good accordance with the experiments reported earlier. By completing the scheme with a reaction step accounting for the precipitation and dissolution of a ferroin-tribromide salt, the batch oscillations found at high concentrations of reactants can also be simulated.}, year = {1992}, pages = {1725-1729} }
