Abstract
Responses to single and periodic pulse perturbations have been studied experimentally and numerically for the reaction of chlorine dioxide and iodide ion in a stirred tank reactor. Excitability with transient oscillations was obtained for perturbations by chlorine dioxide or chlorite, while stimulation by iodide produced no excitable response. Periodic stimulations of the reaction by chlorite display bursting behavior. The experimental observations are in agreement with numerical simulations.
