Abstract
Metal organic frameworks (MOFs) based on iron as a central metal ion and 1,2,4,5-tetrabenzenecarboxylic acid as ligand was successful synthesized, characterized and studied as adsorbent for the removal of lead ions in aqueous solution. 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 2+ adsorption affinity. The removal of Pb 2+ from aqueous solutions varied with concentration, contact time and temperature. All adsorption studies were carried out in batch experiments.
