摘　　要：合成复盐K3Fe(C2O4)33H2O,利用TG-DTG技术分析它们在氮气气氛中的热分解过程,并用微分法中的Achar法和积分法中的Coats-Redfern法对热分解的非等温动力学数据进行研究,推测出可能的热分解反应机理,求出反应的表观活化能。The thermal decomposition processes of the complex have been studied by use of TG-DTG technique. The non-isothermal kinetic data have been analyzed by comparison of the Achar method and Coats-Redfern method. The possible reaction mechanism was suggested and the apparent activation energy of the reaction was obtained.
