| 摘 要： | 系统地研究了反应物、催化剂以及温度对封闭体系BZ振荡反应的影响,振荡反应的最佳初始条件为:[H2SO4]=0.8 mol/L,[CH2(COOH)2]=0.175 mol/L,[KBrO3]=0.06 mol/L,0.004 mol/LCe(SO4)2,温度为303 K.振荡周期与主要反应物浓度之间的动力学方程:Tp=kC-0.635KBrO3×C-0.478CH2(COOH)2×C-0.505H2SO4@一般说来,主要反应物浓度对振荡反应参数影响不大,但催化剂铈的浓度变化对振荡反应参数有明显影响.

| Abstract: | The Belousov-Zhabotinsky oscillating reaction was investigated in a closed system. The parameters of the BZ oscillating reaction were measured as a function of the metal ion catalyst, the reactants and temperature. Some kinetic data and kinetic parameters were obatined. The results are discussed based on the FKN mechanism and the kinetic theory. |
