106RuO4 vapour sorption by inorganic adsorbents

Data from the literature have been collected related to the sorption of RuO4 vapours on different, mainly inorganic, materials. Silica gel and silica gel impregnated with iron(III) oxide appear to be the most suitable for the sorption of RuO4 vapours from waste gases from solidification processes. The adventage of nonimpregnated silica gel is its possible regeneration. Impregnated silica gel has a higher adsorption capacity but sorption is most efficient at temperatures above 200 degC. (Ha)
