A new type of oxyhalogen oscillator: The bromite-iodide reaction in a continuous flow reactor

Article abstract of DOI:10.1021/ja00030a021

The reaction between bromite and iodide ions in a flow reactor shows two steady states and sustained oscillations in pH, redox potential, and [I^-]. The oscillatory behavior is extremely sensitive to the inflow ratio [BrO₂^-]/[I^-], the flow rate, the initial pH of the input solutions, and the stirring rate. Batch experiments suggest that the system behaves in several respects like the analogous chlorite-iodide oscillator. The bromite-iodide system, however, is also a pH oscillator and is the first oxyhalogen oscillator to oscillate in the neutral and basic pH range.
