摘要
采用TG–DSC方法研究了K3[Fe(C2O4)3].3H2O和K3[Cr(C2O4)3].3H2O两个配合物的热分解反应过程,对其中部分热解过程进行了动力学计算。由Friedman、Ozawa-Flynn-Wall、ASTME698三种方法得出峰温时的活化能值与指前因子值。应用Achar方法计算拟合得到了比较合理的机理函数。
The thermal decomposition reactions and its konetic evaluation of the complexes K3 [Fe（C2O4）3]·3H2O and K3 [Cr （C2O4）3]·3H2O has been investigated with TG-DSC methods. The decomposition reaction parameters lgA and Ea （kJ/mol） of all steps of K3[Fe （C2O4）3]·3H2O and K3 [Cr （C2O4）3] ·3H2O were evaluated by Friedman,Ozawa-Flynn-Wall,ASTME698 methods and their optimally kinetic function were fitted by Aehar method, they were belong to Bna.
