摘要：Four complexes of rare earth bromides with amino acids, REBr(3) . 3L . 3H(2)O (RE = La, Nd; L = glycine or alanine) were prepared and characterized by means of chemical analysis, elemental analysis, molar conductivity, thermogravimetry, IR spectra and X-ray diffraction. Their thermal decomposition kinetics from ambient temperature to 500 degrees C were studied by means of TG-DTG techniques under non-isothermal conditions. The kinetic parameters (activation energy E and pre-exponential constant A) and the most probable mechanisms of thermal decomposition were obtained by using combined differential and integral methods. The thermal decomposition processes of these complexes are distinguished as being of two different types, depending mainly on the nature of the amino acid.
