摘要
The thermal decomposition behaviour of europium p-chlorobenzoate complex with l, 10-phenanthroline and its kinetics were studied in nitrogen by non-isothermal thermogravimetry. Its thermal decomposition occurs mainly in three steps.. The intermediate and residue for each step of decomposition were identified from TG curve. The kinetic parameters were obtained from analysis of the TG-DTG curves by the Achar method. the Madhusudanan- Krishnan-Niman (MKN ) method and Ozawa method respectively. The most probable mechanisms function for the first and second stage were suggested by comparing the kinetic parameters.
