Abstract
In the present study, removal of metal ions Pb (II) using nanostructured γ-alumina was investigated in a fixed-bed
column. Comparison of Thomas, Yoon-Nelson, and Adams-Bohart models with experimental kinetic results was
done, and model parameters were evaluated by linear regression analysis for Pb2+ adsorption in different bed
heights, initial concentrations, and flow rates. The obtained experimental data are in good agreement with Thomas
and Yoon-Nelson models, but in the case of Adams-Bohart model, low correlation coefficient is observed.
