Abstract

This study investigates the potential of Unwana clay, sourced from Akanu Ibiam Federal Polytechnic in Ebonyi State, for the adsorption and sequestration of heavy metals. Utilizing a batch method at ambient temperature, we examined the sequestering process. The experimental results were found to fit the Langmuir isotherm model, indicating a high affinity for metal ion adsorption. Specifically, the maximum adsorption capacities (Q?) were determined to be 61.3 mg Pb(II) g?? and 26.8 mg Cu(II) g?? at a pH of 7.0 and a temperature of 25?C, using Unwana clay with a particle size of 200 mesh. The findings demonstrate that Unwana clay can effectively adsorb significant amounts of heavy metal cations from aqueous solutions. These results suggest that Unwana clay is a promising sorption material for heavy metals, potentially paving the way for new commercial applications and environmental remediation strategies.
