Thermal desorption Auger electron spectroscopy (TDAES) was used to investigate the circumstances under which mercury is adsorbed on the surface of iron in the temperature interval of 85 to 298 K. The effects of chlorine and oxygen modifications on the iron surface have also been investigated within the same temperature interval. It was seen that chlorine reduced the adsorption of mercury on polycrystalline iron at 85 K, as did oxygen. On the clean iron system at 298 K, only one monolayer (ML) of mercury adsorbed. The physisorption of mercury on chlorine and oxygen layers at low temperatures (LTs) is discussed in combination with the calculated activation energies of desorption, as well as the factors affecting the mechanism of adsorption at room temperature.
