复盐K_2Cu(C_2O_4)_2·2H_2O的热分解动力学研究

Study on the Thermal Decomposition Kinetics of Double Salts K_2Cu(C_2O_4)_2·2H_2O

合成了复盐K2Cu(C2O4)2·2H2O,利用TG-DTG技术分析研究了它们在氮气气氛中的热分解过程,用Freeman-Carroll和Achar-Brindley-Sharp-Wendworth两种方法确定了复盐热分解反应的活化能(E)、反应级数(n)和频率因子(A)等动力学参数,通过线性拟合得到其相关度均大于0.99,具有良好的动力学一致性.

K_2Cu(C_2O_4)_2·2H_2O was synhesiied.The thermal decomposition of K_2Cu(C_2O_4)_2 · 2H_2O was studied in N_2 by using TG and DTG. The activation energies (E), order of reaction (n), frequency gene (A) was confirmed, and the linearity pertinence coefficienty are all bigger than 0.99. The kinetic consistency is excellent.
