In the present paper the performance of a new functionalized material Fe-IR-120(Na)-DEHPA in the removal process of As(V) from aqueous solutions, has been investigated. The new material was obtained trough impregnation of Amberlite IR-120(Na) with di(2-ethylhexyl) phosphoric acid (DEHPA) trough the dry method. Trough impregnation of the Amberlite IR-120(Na) was obtained a resin with two functional groups which was further loaded with Fe(III) ions because of the high affinity of arsenic towards iron. The physicochemical methods of analysis (FTIR spectroscopy, EDX and SEM) approved that the impregnation with DEHPA and the iron loading, respectively, occurred. By applying the kinetic model to the experimental data it was found that the removal of As(V) ions by Fe-IR-120(Na)-DEHPA follows the pseudo-second-order rate kinetics. The linear Langmuir and Freundlich isotherm models were used to represent the experimental data and these could be well interpreted by the Langmuir isotherm. RL values between 0 and 1.0 further indicate a favorable adsorption of As(V) ions onto Fe-IR-120(Na)-DEHPA. The maximum As(V) ions uptake calculated from Langmuir model was 21.8 μg/g.
