Biosorbents (fiber, treated fiber, and charcoal) from the Leucaena leucocephala tree were prepared in this study. The potential of the biosorbents as metal capture (removal percentage %R ) for chromium (III) (Cr +3 ) from aqueous solution was examined. The concentrations of the Cr +3 solutions were measured before and after the adsorption to investigate the %R using atomic absorption spectrometry (AAS). Moreover, the specific surface area ( A ) of the biosorbent samples was evaluated after measuring the adsorbed acetic acid onto the samples. From the results, A and %R were found in the order of charcoal > treated fiber > fiber. The highest values of A and %R were about 423 m 2 g −1 and 97%, respectively. This finding suggested the high potential of Leucaena charcoal usage as chromium ions capture compared to fibers and treated fibers.
