Kinetic parameters for non-isothermal decomposition of cobalt(II), nickel(II) and palladium(II) complexes with 2-furaldehyde thiosemicarbazone

Abstract

The 2-furaldehyde thiosemicarbazone complexes of Co^II, Ni^II and Pd^II have been subjected to thermal decomposition studies in air using TG, DTG and DTA techniques. The kinetic parameters for both stages of decomposition of these complexes were computed by a weighted least-squares method using the general approach as well as the Coats-Redfern, Freeman-Carroll and Horowitz-Metzger equations. The results indicate that the values of the kinetic parameters obtained by these different methods agree well. It was also found that both stages of decomposition of these complexes follow first-order kinetics.
