Abstract
A major concern for both humans and aquatic life can result from the presence of several
metal ions in an aquatic environment that exceeds the allowed limit. The most efficient
way to remove minute levels of hazardous metals from wastewater is through adsorption.
The primary goal of this thesis work is to chemically modify sugarcane bagasse in order
to create a low-cost, highly effective adsorbent for the removal of Al (III) from an
aqueous solution. Both xanthated and charred sugarcane bagasse have been prepared as
adsorbents. Adsorbents are characterised using FTIR, EDS, and SEM. For analysis, batch
experimental method was carried out. Utilizing both CSB and XSB, the effect of pH, Al
(III) concentration and contact time have been investigated using both CSB and XSB
adsorbents. For both adsorbents, a 150-minutes maximum duration and a pH of 4 are
found to be ideal. The Langmuir isotherm model is best fitted for equilibrium sorption
data, and maximum adsorption capacities of CSB and XSB are determined to be 50.9
mg/g and 81.0 mg/g, respectively. Studies on kinetic modelling showed that a pseudo second-order kinetic model best fit the experimental data. These findings show that XSB
can be an alternative bio-adsorbent for the elimination of Al(III) from an aqueous
solution.
