Preliminary Column Study and Biosorption Kinetic Profile of Cadmium (II) by Epichlorohydrin-Crosslinked Lumbang (Aleurites molucanna) Chitosan Composite

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 o...

Zusammenfassung: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°C, 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
