Characterization of Fe-MOF was attained by SEM, EDX, TGA and FT-IR techniques. EDX spectrum showed the presence of C, O and Fe, which may facilitate in creating charges and functionalities on the surface of the Fe-MOF for adsorption. The kinetic and thermodynamic parameters were also inves­tigated. The results showed that Fe-MOF has a high Pb<sup>2+</sup> adsorption affinity. The removal of Pb<sup>2+</sup> from aqueous solutions varied with concentration, contact time and temperature. All adsorption studies were carried out in batch experiments.</span></p> ER -
