Abstract:

In this paper, the effects of hydroxylamine sulfate and hydrated hydrazine on the B-Z reaction are studied. Hydroxylamine sulfate and hydrated hydrazine can react with BrO~-_3 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.

Key words: Hydroxylamine sulfate, Hydrated hydrazine, B-Z reaction
