摘要
采用TGDTG和DTA技术研究了[Eu2(mBrBA)6(H2O)2(phen)2]配合物(mBrBA代表间溴苯甲酸根离子;phen代表1,10邻啡罗啉)在静态空气中的非等温热分解过程及动力学,根据TG曲线确定热分解过程的中间产物及最终产物,运用热分析动力学数据处理方法,确定了第1步热分解的动力学模型为SB(m,n).
The thermal decomposition of the [Eu_2(m-BrBA)_6(H_2O)_2(phen)_2](m-BrBA=m-bromobenzoate;phen=1,10-phenanthroline)and its kinetics were studied under the non-isothermal condition in air by TG-DTG and DTA methods.The intermediate and residue for each decomposition were identified from TG curve.By the kinetic method of processing thermal analysis data put forward by Malek et al,it was defined that the kinetics model for the first-step thermal decomposition is SB(m,n).
