Abstract
IT seems to have been assumed in most studies of physical adsorption that adsorption of mercury vapour is unimportant. In only a few cases has any attempt been made to study the adsorption of mercury or its influence on the adsorption of other vapours. Coolidge1 found that the adsorption of mercury vapour at 298 K on charcoal is negligible and more recently Miles2 has shown that the presence of mercury vapour did not affect the adsorption isotherms of hydrocarbon vapours on charcoal. A similar result has been obtained in our laboratories for the adsorption of nitrogen at 77 K on aluminas and silicas. With certain chromium oxide gels, however, we have now established that a significant amount of mercury vapour adsorption takes place at temperatures around 298 K.
