The oscillation behavior of the bromate–cerium–oxalic acid system was simulated within the FKN framework with bromine-hydrolysis control, where a radical-chain reaction of HOBr with oxalic acid and the formation of HCO<SUB>2</SUB>· by the reduction of Ce(IV) were assumed. When [(COOH)<SUB>2</SUB>]=0.03 mol dm<SUP>−3</SUP> and <I>k</I><SUB>13</SUB>=0.075 s<SUP>−1</SUP> (<I>k</I><SUB>13</SUB>: the rate constant of bromine removal), the oscillation behavior was qualitatively consistent with the experimental results. Excitability in the reduced and oxidized steady states, induced by a sudden change in the concentration of bromine, was simulated. No bistability was found. When [(COOH)<SUB>2</SUB>]=0.03 mol dm<SUP>−3</SUP>, no hysteresis near the bifurcation points was observed. However, when [(COOH)<SUB>2</SUB>]=0.001 mol dm<SUP>−3</SUP>, hysteresis was observed in the transition between the oxidized steady state and the oscillatory state.
