The eight solid complexes of zinc with L-alpha-methionine or L-alpha-histid
ine were prepared. The thermal decomposition processes of these complexes w
ere determined by means of TG-DTG. The results show that their decompositio
n processes can be divided into three steps except for the complex Zn(Met)(
2) the decomposition of which is completed in one step. All the final produ
cts are ZnO.
