Abstract
The reaction of bromate, sulfite, and ferrocyanide ions in a continuous stirred tank reactor (CSTR) exhibits sustained oscillations at temperatures of 20, 30, and 40 OC. The oscillations, the behavior in a closed (batch) system, and the observed bistability in a CSTR are all in excellent agreement with simulations using a nine-step mechanism in which the reaction of BrO,- with Fe(CN)6& plays a key role. The relationship between the present system and the 'mixed Landolt" oscillator, in which bromate is replaced by iodate, is discussed.
