Equilibrium adsorption—desorption data for HCN on BPL activated carbon and ASC whetlerite carbon are reported for various temperatures. Wo values calculated from the Dubinin-Polyani equation for BPL activated carbon and for ASC whetlerite carbon are 0.42 and 0.35 ml/g respectively at temperatures from 0 to 122°C. The heats of sorption were obtained from the Clausius Clapeyron equation. The heat of sorption approximates to the heat of liquefaction at high surface coverage in both carbons. Significant increases above this are observed at surface coverages below 0.3, in the case of ASC whetlerite, and below 0.05, in the case of BPL activated carbon. |
