DTA, TG - DTG techniques were used to study thermal oxidation degradation process and kinetics of complex Pd (NH3)4Cl2·H2O in air. It has been found that thermal oxiation degradation process of complex Pd (NH3)4Cl2 · H2O is of four steps. Treated with Coats -Redfern equation we found that the apparent degradation reaction orders are 1.1、 0.53、 0.55、 1.1 and the activation energies are 74.4 kJ/mol、 100.7 kJ/mol、 170.7 kJ/mol、 312.7 kJ/mol of complex Pd (NH3)4Cl2·H2O.
