Abstract:

A new chemiluminescence oscillation in the Belousov-Zhabotinsky(B-Z) reaction(reduction of bromate by malonic acid) catalyzed by Ru(bpy)2+3 is reported. The effects of concentrations of Ru(bpy)2+3, KBrO3, malonic acid and H2SO4 on chemiluminescence oscillation reaction were studied. The possible mechanism of chemiluminescence oscillation was also discussed. The chemiluminescence oscillation, which is due to the reduction of Ru(bpy)3+3 by some strongly reducing radical with formation of the emitting excited state of Ru(bpy)2+3, shows a very peculiar time behavior.

Key words: B-Z oscillating reaction, Chemiluminescence oscillation, Ru(bpy)2+3
