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 Pb 2 + 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.
