Adsorption Study of Pb (II) Ion Removal From Lead Solution Using a Blend of Activated Carbon and Chitosan From Mussel Shells

Article scientifique 2024 Anglais

Résumé

A batch adsorption study was carried out to investigate the adsorption of lead (II) ions on the blend of activated carbon and chitosan from the mussel shell of the lead water solution. The optimum chitosan/activated carbon blend dosage was 5 g (2.5 g activated carbon and 2.5 g chitosan). At optimum dosage, the percentage uptake was 83.75%, and 0.134 mg/l of Pb 2+ was removed, while at an equilibrium contact time of 120 minutes, the percentage uptake was 98.75%. The data generated was used for isotherm studies and kinetic modelling. The Langmuir isotherm fits best with an R 2 value of 0.9776, and the adsorption was favourable at 0.0842 kJ/mol. Also, the adsorption process follows the Pseudo second-order kinetic model with an R 2 value of 0.9981.
