Cu(II) complex with a triazolic ligand was synthesised and characterized. The stoichiometric composition of this complex was deduced from the thermal behaviour, FT-IR spectroscopy, complexometric titration and evolved gases analysis. The kinetic analysis of the degradative process of the Cu(II) complex was investigated using the thermogravimetric data in air for the substance's decomposition in non-isothermal conditions. The kinetic parameters were obtained by means of different multi-heating rates methods (which are using five curves measured at different heating rates, beta=5, 7, 10, 12 and 15 degrees C-min(-1)): isoconversional methods (model-free) Kissinger-Alcahira-Sunose, Flynn-Wall-Ozawa and Friedman, respectively the non-parametric kinetics method (NPK), which allows a separation of the temperature, respective conversion dependence of the reaction rate. The values of the obtained kinetic parameters from the four applied methods are in a good agreement.
