【摘要】 本文主要对过渡金属Fe2 + 、Mn2 + 对SO32 - 液相催化氧化动力学进行了研究。通过研究发现并证实了Fe2 + 离子对SO32 - 液相催化反应是一级 ,Mn2 + 离子则是二级反应。当以Fe2 + +Mn2 + 为催化剂时 ,反应级数为 1.2级。酸度对反应的影响较大 ,随着酸度伸高反应显著。同时测定了以Fe2 + 、Mn2 + 为催化剂时的活化能分别为 :Ea(Fe) =10 .5kJ mol,Ea(Mn) =9.91kJ mol更多还原

【Abstract】 Catalytic oxidation of dynamics of SO 3 2- with transition metal elements Fe , Mn in aqueous solution have been studied in this paper. After study, we find and confirm that the catalytic reaction of Fe(II) to SO 3 2- is the first grde and Mn(II) is the second grde .But if the catalyst is Fe(II)-Mn(II), the procession of the reaction is grde 1.2. Acidity greatly affects the reaction . Meanwhile the activation energy with the catalyst Fe(II), M(II) are determined as follows: 10.5kJ/mol , 9.91kJ/mol .更多还原
