Abstract
At a temperature of 30°C or higher,the reaction of sulfite, iodate,and ferrocyanide exhibits sustained oscillation in a CSTR.The system maybe thought of as a FefCN)^ perturbation of the bistable Landolt(S032~-I03~)reaction in which the ferrocyanide serves to consume the I2produced in the reduction of iodate, thereby“resettingtheclock".There action maybe monitored with pH,redoxoriodide-selective electrodes, or spectrophotometric measurement of iodine,ferrocyanide, or ferricyanide.
