In this study, an iron-based porphyrinic metal–organic framework, called PCN-600(Fe), was prepared by a solvo-thermal method and fully characterized. The bio-inspired and mesoporous PCN-600(Fe) was then applied for the adsorptive removal of sodium warfarin, a synthetic anticoagulant, from aqueous solutions. Various experimental parameters affecting adsorption such as the pH of the sample, contact time, initial analyte concentration, and amount of sorbent were investigated and optimized. The adsorption of sodium warfarin onto PCN-600(Fe) was confirmed to obey the Langmuir isotherm model with pseudo second-order kinetics with a maximum adsorption capacity of 370 mg g⁻¹. Porosity, Lewis acidity of iron sites, and electrostatic interactions possibly play vital roles in such a high tendency of PCN-600(Fe) toward sodium warfarin adsorption. Finally PCN-600(Fe) was successfully applied to remove this analyte from a few real samples with removal better than 92 percent.

铁基卟啉金属有机骨架在水溶液中去除华法林的应用

在这项研究中，通过溶剂热法制备了铁基卟啉金属有机骨架PCN-600（Fe），并对其进行了充分表征。然后将具有生物启发性的介孔PCN-600（Fe）应用于从水溶液中吸附去除华法林钠（一种合成的抗凝剂）。研究和优化了影响吸附的各种实验参数，例如样品的pH，接触时间，初始分析物浓度和吸附剂的量。证实华法林钠在PCN-600（Fe）上的吸附符合Langmuir等温模型，具有伪二级动力学，最大吸附容量为370 mg g ^-1。在PCN-600（Fe）如此高的华法林钠吸附趋势中，孔隙度，铁位点的路易斯酸度和静电相互作用可能起着至关重要的作用。最终，成功将PCN-600（Fe）应用于一些实际样品中的分析物去除，去除率优于92％。
