| Abstract: | The ternary solid-state complex Tb(Tyr)(Gly)3Cl3???????????3H2O (s) has been synthesized with TbCl3??????????6H2O(s), taking Tyr and Gly as reactants.The thermal decomposition processes of the complex have been studied by use of TG-DTG technique. The non-isothermal kinetic data has been analyzed by employing of the Achar method and Coats-Redfern method. The possible reaction mechanism was suggested and the apparent activation energy of the reaction was obtained. |
