Autocatalytic oxidation of Fe(phen)32+ (ferroin) by bromate has been investigated in a continuous flow stirred tank reactor (CSTR). A closed region of bistability exists in the plot of input stream concentrations of ferroin and bromate. The bromate-ferroin-bromide system exhibits bistability and high amplitude oscillations over a broad range of concentrations. As a first approximation a revised Oregonator type model extended by reactions of ferroin and ferriin describes the system. However, further reactions have to be taken into consideration for a quantitative description.
