采用 TG- DTG和 DTA技术研究了 Zn[NFA]2 .5H2 O(NFA=C16H18FN3O3氟哌酸 )在静态空气中的热分解过程及非等温动力学 ,根据 TG曲线确定了热分解过程中的中间产物及最终产物 ,运用 Achar法与 Madhusudanan- Krishnan- Ninan(MKN)法对非等温动力学数据进行分析 ,推断出第二步热分解的动力学方程为 da/dt=Aexp(- E/RT) (1 -α)
The thermal decomposition and non-isothermal kinetics of Zn [NFA] 2.5H2O (NFA = C16H18FN3O3 norfloxacin) in static air were studied by TG-DTG and DTA techniques. The TG The kinetic equation of the second step thermal decomposition was deduced as follows: da / dt = Aexp (- E / RT), and the kinetic equation of Acharp and Madhusudanan- Krishnan-Ninan (1-α)
