摘要
研究KMnO4和双氧水在酸性条件下的自催化反应动力学,以及反应的诱导期与两种反应物浓度的关系,提出在各种浓度条件下,用KMnO4分析H2O2含量靠自身催化的分析方法.改进后的方法,适用浓度范围宽,反应速度快,滴定分析误差小.
This paper reports the study on the kinetic of self catalyzed oxidation of hyperoxide by KMnO 4 in acid solution.The relation between the reaction induction period and the concerntrations of reactants H 2O 2 and KMnO 4 has be examined.And the determination method of H 2O 2 by self catalyzed oxidation by KMnO 4 has been established.
