The different parameters affecting the adsorption were examined. Equilibrium data were fitted into Langmuir, Freundlich, D-R and Temkin isotherm models for four different examined temperatures (from 20 to 50 degrees C). Adsorption of 2,4-D was well described by Freundlich isotherm as a physical adsorption, whereas Langmuir model well described the adsorption of Fe(III) at four different temperatures from 20 to 50 degrees C. Pseudo-first-order, pseudo-second-order, intra-particle diffusion and Elovich models were used to analyse kinetic data. The adsorption kinetics for both pollutants were found to match pseudo-second-order kinetic model with high correlation (between 0.975-0.999 for Fe(III), between 0.995-0.999 for 2,4-D) than the other models. In addition, the thermodynamic parameters were evaluated and discussed for the thermodynamically modeling of the adsorption processes.en10.1016/j.surfin.2017.03.011info:eu-repo/semantics/closedAccessWaste disposalActivated carbonAdsorption equilibriumArticle8182192Q1WOS:000408917900025N/A
