A new porous indium metal organic framework namely (AUBM-1) was successfully synthesized via a solvothermal reaction of pyromellitic acid and indium chloride. Single crystal X-ray analysis revealed the formation of a 3D framework with a pts topology. The resulting MOF structure showed high chemical stability at different pH values. Thus, the activated indium MOF was applied for As removal from water for the first time and showed a high arsenate uptake capacity of 103.1 mg g−1 at neutral pH, which is higher than the commercial adsorbents (usually less than 100 mg g−1 at neutral pH). Finally, the kinetics and thermodynamic studies revealed that the As adsorption was an endothermic process and followed a pseudo-second-order kinetic model.

高度稳定的基于铟的金属有机框架,可有效去除水中的砷†

通过均苯四酸和氯化铟的溶剂热反应成功合成了一种新型多孔金属铟有机骨架材料(AUBM-1) 。单晶 X 射线分析揭示了具有pts拓扑的 3D 框架的形成。由此产生的 MOF 结构在不同 pH 值下表现出较高的化学稳定性。因此,活化的铟MOF首次应用于水中除砷,并在中性pH下表现出103.1 mg g -1的高砷酸盐吸收能力,高于商业吸附剂(通常小于100 mg g -1)中性 pH 值)。最后,动力学和热力学研究表明,As吸附是一个吸热过程,遵循准二级动力学模型。
