Determination of Mechanism Function And Kinetic Parameters of Thermal Deomposition of The Zn[NFA]_2·5 H_2O with Non-isothermal TG And DTG Curves

采用TG -DTG技术研究了ZnL2·5H2O(L=C16H18N2O3F)配合物的热分解过程 ,对其进行了热分解非等温动力学研究。运用Achar法和Madhusudanan -Krishan -Ninan法 ,对非等温动力学数据进行分析 ,推断出ZnL2·5H2O的第二、三步热分解反应动力学方程 。

The thermal behavior of Zn2·5 H2O(NFA=C16H18FN3O3,norfloxacin)in air atmosphere was investigated by TG-DTG techniques.The non-isothermal kinetic data were analyzed by means of the Achar method and the Madhusudanan-Krishan-Ninan(MKN)method.The possible reaction mechanisms were investigated by comparing the kinetic parameters.Mathematic expressions of the thermal decomposition were derived from the kinetic compensation effects.
