摘要：

Experimental observation shows that bromomalonic acid (BrMA) is one of the sources of photo-induced Br- ion in the photosensitive Belousov-Zhabotinsky reaction. The rate of Br- production by visible light was measured using a Br--ion-selective electrode in a solution containing BrMA, H2SO4 and Ru(bpy)(3)SO4 but no oxybromine species. The order of reaction was 1 for [BrMA] and [H+], and about 1/2 for the light intensity and [Ru(bpy)(3)(2+)]. Two types of probable photocyclic mechanisms are proposed.
