Studies of Thermal Analysis on Kinetics for Ternary Solid Complex Pr(Me_2dtc)_3(phen)

Ternary solid Rare-earth complex Pr(Me_2dtc)_3(phen) (Me_2dtc=dimethyldithiocarhamat -e,phen=phenanthroline) has been synthesized and characterized by Chemical analysis and elemental analysis.In addition,its thermal behavior was investigated by TG-DTG method,which was proved to afford P_(r2)S_3 by X-ray powder diffraction method after one decomposition stage.Furthermore,the decomposition process was studied by"model-free isoconversional method"in order to obtain the apparent activation energy (E),the pre-exponential constant (A),the mostprobahle mechanism function and the kinetic model function.
