Abstract

Bioremediation of heavy metal pollution remains a major challenge in environmental biotechnology.
The ability of chemically activated sawdust to remove chromiumfromaqueous solutionwas investigated.
Experiments were carried out as a function of adsorbent dosage, initial concentration of chromiumand
contact time. The mechanism of metal sorption by chemically activated sawdust gave good fits for
Langmuir, Freundlich andLagergrenmodels. The bioadsorption efficiency of chromiumto the sawdust
was decreased as the initial concentration ofmetal ions increased. The percentage removal was increased
(79% to 97%) with an increase in contact time (20 to 100 min) at an initial Cr (VI) concentration of 20
mg/L.According to Langmuir isotherm, the monolayer saturation capacity (Qo) was 33.55mg/g. The
study showed that chemically activated sawdustwasmore favourable for the adsorptionof chromium(VI)
from the aqueous solutions.
