Abstract

A new polyoxovanadates-based metal–organic framework (POV-MOF) Ag₂(Tipa)₂(V₆O₁₆) (Ag-V-MOF) with unique curly layered structure has been designed by virtue of a stellated tridentate N-containing ligand of tri-(4-(1-H-imidazol-1-yl)phenyl)amine (Tipa). After effectually alkali-treated by sodium hydroxide solution in certain concentrations, the modified materials, named EA_x-Ag-V (x = 1, 2, 3, and 4) were obtained expectedly, among which EA₃-Ag-V exhibited a gratifying performance in adsorption creatinine, a major uremic toxin generated during hemodialysis treatment in patients with renal failure. The maximum adsorption capacity of creatinine was 140.45 mg g⁻¹ for EA₃-Ag-V, and it also displayed a good reusability and stable adsorption performance in a wide pH range. In this work, two statistical models of definitive screening design (DSD) and central composite rotatable design (CCRD) were applied effectively to determine the effect of mixed co-existing substances to the adsorption process. Based on the batches of experiments and characteristic measurements, as well as fractal dimension analyses of the materials, the underlying adsorption mechanism between creatinine and EA₃-Ag-V was detailedly revealed, including π-π interaction, H-bonding force, and electrostatic attraction.

Graphical Abstract

A novel 2D layered polyoxovanadate-based metal-organic framework derivant has been designed and synthesized successfully, in which the material exhibited highly effective specific adsorption for a typical uremic toxin creatinine.

利用三(4-(1-H-咪唑-1-基)苯基)胺(Tipa)的星状三叉含 N 配体，设计了一种具有独特卷曲层状结构的新型聚氧化钒金属有机框架（POV-MOF）Ag2(Tipa)2(V6O16)（Ag-V-MOF）。经一定浓度的氢氧化钠溶液碱处理后，可望获得改性材料，命名为 EAx-Ag-V（x = 1、2、3 和 4），其中 EA3-Ag-V 在吸附肾衰竭患者血液透析治疗过程中产生的主要尿毒症毒素肌酐方面表现出色。EA3-Ag-V 对肌酐的最大吸附容量为 140.45 mg g-1，而且在较宽的 pH 值范围内也表现出良好的重复使用性和稳定的吸附性能。本研究有效地应用了确定性筛选设计（DSD）和中心复合可旋转设计（CCRD）两种统计模型来确定混合共存物质对吸附过程的影响。根据成批实验和特征测量结果以及材料的分形维度分析，详细揭示了肌酐与 EA3-Ag-V 之间的内在吸附机理，包括π-π相互作用、H 键力和静电吸引。
