EGA/MS investigations on the thermal degradation of diammoniumhexachloroplatinate

The thermal degradation of diammoniumhexachloroplatinate (NH4)(2)PtCl6 is u sed in technical scale for the production of the pure platinum metal [1] an d for this reason of great interest. Our investigations have been focused on the influence of the different atmo spheres (oxidizing, inert or reducing) used in the technical processes towa rds the degradation mechanism and the evolved volatile degradation products . The second main aspect of our investigations was the evolution of volatile platinum species. Regarding the different frequencies of platinum allergies related to the different technical processes, the evolution of volatile pl atinum species is of great importance, due to the supposed allergic potenti al of this substances [2-4].
