摘要

成功合成了以铁为中心金属离子，1，2，4，5-四苯羧酸为配体的金属有机骨架（MOFs），并对其进行了表征和研究。采用扫描电镜、能谱仪、热重分析和红外光谱等方法对Fe-MOF进行了表征。EDX光谱显示了C、O和Fe的存在，这可能有助于在Fe-MOF表面产生电荷和官能团以进行吸附。并对动力学和热力学参数进行了研究。结果表明，Fe-MOF对Pb2+具有较高的吸附亲和力。Pb2+从水溶液中的去除随浓度、接触时间和温度的变化而变化。所有的吸附研究都是在分批实验中进行的。

Iron based metal organic framework as an effective lead ions remover from aqueous solution: Thermodynamic and kinetics studies

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.
