Abstract—The adsorption equilibrium characteristics for single and binary components of phenol and lead ions on Bamboo Chitosan Composite Bead (BCB) were studied. The surface areas of BCB beads increased with the increasing amount of Bamboo Activated Carbon (BAC) contained. Adsorption equilibrium data for the single component of phenol and lead ions on the adsorbents could be represented by the Langmuir equation. The maximum adsorption amount of lead ions on chitosan bead was 0.85 mol/kg. Multicomponent equilibrium data were correlated by the extended Langmuir and Ideal Adsorbed Solution Theory (IAST). The IAST gave the best fit to our data. The adsorption capacity of lead ions on the different adsorbents was in the following order: chitosan (0.85) > BCB-1 (0.49) > BCB-2 (0.23) > BAC (0.2 mol/kg). On the other hand, that of phenol was: BAC (1.81) > BCB-2 (0.93) > BCB-1 (0.61) > chitosan (0.03 mol/kg).
