Resumo

Thermogravimetry (TG) and other analysis techniques have been used to study the reaction of mercury with Pt and a PtIr alloy. The results suggested that, when heated, the electrodeposited Hg film reacts with Pt or with PtIr to form products of different stabilities, indicated by at least three weight loss steps. In the first step, between room temperature and 170°C, only the bulk Hg is removed. From this temperature to about 280°C the mass loss can be attributed to the desorption of a monolayer of mecury. The last step, from 280 to ≈600°C, can be ascribed to the removal of Hg from a solid solution with Pt and PtIr alloy. © 1995.
