Abstract
Abstract (portuguese)
Foram preparados os ditizonatos de Hg (I), Ag (I) e Bi (III). Termogravimetria (TG), termogravimetria derivada (DTG), calorimetria exploratória diferencial (DSC), difratometria de raios X pelo método do pó e análise elementar foram usados para caracterizar e para estudar a estabilidade térmica e a decomposição térmica da ditizona e destes ditizonatos.
Abstract (english)
Solid dithizonates of Hg(I), Ag(I) and Bi(III) have been prepared. Thermogravimetry (TG), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), X ray diffraction powder patterns and elemental analysis have been used to characterize and to study the thermal stability and thermal decomposition of the dithizone and of these dithizonates.
