In this study, the biosorption potential of lumbang (Aleurites molucanna)-derived activated carbon towards Cd(II) in aqueous solution was investigated by coating and crosslinking the adsorbent with chitosan and epichlorohydrin, respectively. Batch adsorption studies were performed and the effects of various parameters were evaluated. Results have shown that the optimum biosorption potential occurs at pH: 6.0, contact time: 45 min, temperature: 40 oC, adsorbent dosage: 12 g/L, and initial Cd(II) concentration: 5 ppm. The biosorption kinetic profile obeyed the pseudo second-order kinetic model (R2=96.87%, p<0.001). Preliminary column study and waste water analysis revealed significant removal of Cd(II), with 89.59% and 49.08% of Cd(II) adsorbed and desorbed, respectively. There were significant reductions in the biochemical and chemical oxygen demand values of the waste water before and after passing through the column.
