Hassan, T. Farid, A. El-Bellihi] The thermal decomposition of γ-irradiated and unirradiated complexes of mandel-hydroxamic acid (HMA), Co(HMA)2.1/2H2O, Mn(HMA)2.2H2O, Ba(HMA)2.2H2O and Cd(HMA)2.2H2O have been studied thermogravimetrically (under isothermal conditions). The thermal dehydration of each complex occurred in one step, while the decomposition of dehydrated complexes occurred in two steps. The kinetic parameters for dehydration were computed by different models. The thermal dehydration is regulated by random nucleation A3 for Co-, Mn-, and Cd-complexes and by phase-boundary (R3) for Ba-complex. The effect of γ-irradiation on the kinetic parameters of thermal decomposition is discussed. Radiation did not modify the mechanism of the reaction but accelarated the dehydration steps in the case of Mn- and Co-complexes. Akadémiai Kiadó, 1992 Hassan R.
