Abstract
Carbon adsorbents were produced from Northern Ireland lignite by chemical treatment and physical activation. Their capability to adsorb metals were determined by evaluating the adsorption isotherms obtained when the adsorbents were allowed to reach equilibrium with single component solutions. Similar experiments were conducted with air dried lignite and a commercial activated carbon, Chemviron Filtrasorb 400. Cation exchange was evaluated by following the desorption of cations from the original adsorbent into the metal solutions. Surface area and porosity were characterised by nitrogen adsorption isotherms and mercury porosimetry. The physical features of the surface of the adsorbents were observed by Scanning Electron Microscopy.
