摘要
采用TG-DSC方法研究了K2[Cu(C2O4)2].2H2O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-W all、AST-ME698三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 kinetic evaluation of the complexes K2[ Cu（ C2O4）2]·2H2O and K3[ Cr（ C2O4）3]·3H2O have been investigated by TG -DSC methods. The decomposition reaction parameters lgA and Ea（ kJ·mol^-1 ） of all steps of K2[ Cu（ C2O4）2]·2H2O and K3[ Cr（ C2O4）3]·3H2O were evaluated by Friedman, Ozawa - Flynn - Wall , ASTME698 methods and their optimally kinetic function were fitted by Achar method , they were belong to Bna.
