In this paper oscillating phenomena of the Belousov-Zhabotinskii(BZ) reaction between malonic acid, ferrous o-phenanthroline and bromate ion have been studied. The effects of different atmospheres and the dissociation of ferrous o-phenanthroline ion in acid solution on the oscillation behavior of the reaction are investigated. Experiment results are interpreted in terms of the familiar reaction mechanism. The major results of this work are as follows:
(1) In order to investigate the effect of flow rate of gases on time of initiation (t_(in)), time period (t_p) and life time (t_l) of the oscillation, nitrogen and hydrogen were bubbled into the reaction system. The effect of stirring rate on t_(in), t_p and t_l in the same atmospheres was also studied. The experiment results are shown in Fig.1 These results show that in nitrogen or hydrogen atmosphere, flow rate and stirring rate do not obviously affect t_(in), t_p and t_l at fixed initial concentrations of various reagents. So it can be concluded that nitrogen and hydrogen are inert for the oscillation behavior of the BZ reaction.
