The presents study was conducted to investigate removal of iron(III) ions from aqueous solutions by adsorption on carrot. For this purpose, various parameters were optimized for iron removal. The adsorption behavior of the Fe(III) ions was studied using Langmuir, Freundlich, and Temkin adsorption isotherm models. The thermodynamic parameters of the adsorption were also discussed in this work. The kinetic data was analyzed using pseudo-second-order kinetic model. MINITAB (v. 19) software was employed for prediction and investigation of factor importance in determining of removal ratio of Fe(III) ions. The carrot was characterized by FTIR and FE-SEM.
