The combination of gas-solid adsorption experiments with immersion calorimetry of carbons into liquids of increasing molecular dimensions leads to accurate micropore distributions in the range 0.4-0.8 nm. This technique is used to study the development of the micropore structure during activation of
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
Seventeen kinds of activated carbons of different surface acidity and of known pore-structure were used as adsorbents for gas chromatography. The retention time of various kinds of substrates was determined for each carbon at different temperatures. It was found that surface acidity of carbons has a
