Hydroxylamine sulfate and hydrated hydrazine can react with BrO to produce Br-. They show some analogies with vitamin C in their effects on B-Z reaction, that is, they sbolarly lengthen the induction period and oscillating period,and shorten the life-span of this oscillating reaction.From this reason the conjecture of reaction mechanism that is proposed by Zhao Xuezhuang et al can be confirmed.展开更多
