| 摘 要： | 采用水热法合成了稀土铕、苯甲酸(C7H6O2)和1,2-二(4-吡啶基)乙烯(C12H10N2)的固态新配合物.通过元素分析和化学分析的方法,确定了配合物的组成为Eu(C7H5O2)(3C12H10N2)(H2O)3;用红外光谱和荧光谱等技术对配合物进行了表征,该配合物在室温受激发射红色荧光;用TG-DTG法研究了它的热分解行为;用"非模型等转化率法"研究了热分解脱水过程的动力学,获得其表观活化能和指前因子数值范围、最可机理函数和模型函数.

| Abstract: | The new solid complex were self-assembled from benzoic acid(C7H6O2),1,2-Di-(4-pyridyl)-ethylen(C12H10N2)and corresponding europium chlorides under hydrothermal conditions.The composition of the complex was confirmed to be Eu(C7H5O2)(3C12H10N2)(H2O)3,which is characterized by means of chemical and elemental analyses,FT-IR.Its thermal behavior was investigated by TG-DTG method;Furthermore,the decomposition process was studied by"model-free isoconversional method"in order to obtain the apparent activation ener... |
