摘要
本文采用分光光度方法研究了在氨水-氯化氨介质中铜(Ⅱ)催化过氧化氢还原中性红反应的动力学及机理。实验获得速率方程的通式为:r=k[Cu2+]1.0[NR]0[H2O2]1.0,实验活化能Ea=48.98kJ.mol-1。动力学处理导出的方经验速率方程获得满意的吻合。
We studied the kinetics behaviors of Copper （ Ⅱ） catalyzed reaction between neutral red and H2O2 in the medium NH3 ·H2O - NH4 CI. The common formula of rate law is r = k [ Cu2 ＋ ] 1.0 [ NR ] 0 [ H2O2 ] 1.0. Its activation energy is 48.89kJ. The kinetic mechanism was investigated. The rate equation obtained from either mechanism is in conformity with its rate law.
