✦ Synopsis

Nitrogen isotherms have been determined at 77 K on four active carbons, used as adsorbents in gas masks, before and after n-nonane ~readsorption. The four carbons contain both micro and mesopores. After n-nonane preadsorption, mesoporosity is still observed, together with a, low pressure hysteresis that can be ascribed to the penetration of Nz into the porous system through n-nonane stoppers that block some of the pore entrances. Results have been analyzed by means of the Dubinin-Radushkevich (DR) equation and the OL, method.

Activated carbon cloth is impregnated by dipping in solutions of cobalt acetate or nickel acetate to give a range of loadings. Prepared cloths were used to form filter beds, 20 layers thick, which were exposed to hydrogen cyanide (HCN)-laden air. Challenge concentration was 2 mg L-' HCN in air at 80
