“…In this regard, Alqadami and coworkers performed post‐synthesis modification, abbreviated as performed post‐synthesis modification (PSM), approach to modify NH 2 ‐MIL‐53(Al) with citric anhydride (CAD) through covalent bond formation between –NH 2 group of NH 2 ‐MIL‐53(Al) and carboxylic group of CAD to form mesoporous amide CAD [AMCA‐MIL‐53(Al)] MOF with 126.9 m 2 g −1 BET surface area and 0.283 cm 3 g −1 pore volume (Figure ) . During the pH influence on adsorption capacity, they find that as pH increased from 1.47 to 5.76, the magnitude of Pb II capture on AMCA‐MIL‐53(Al) gradually elevates from 10.8 up to 90.8 mg g −1 , thereafter because of the hydrolysis of Pb II in an aqueous medium, adsorption was slaked.…”

The efficient adsorption of heavy metal ions from wastewater has become a serious challenge from both environmental and biological viewpoints. Recently, porous metal‐organic frameworks (MOFs), with metallic clusters and organic linkers, have been developed as promising structures in the capture of different toxic and hazardous substances, including heavy metal ions, because of their unique features. Here there is a collection for recent progress in the field of water remediation from the variable‐valent metals in polluted water and the corresponding MOFs which are able to remove these pollutant agents from water. Meanwhile, effective factors in the absorption of metal ions are discussed. MOFs are considered to be a promising candidate for metal ions removal from wastewater.

“…Up to now, most of the reported MOFs are constructed from rigid or semi-rigid aromatic carboxylate ligands derived from petrochemical sources; however, the use of other flexible and eco-friendly carboxylate ligands as building blocks or as modulators during MOF synthesis is scarce [ 78 , 79 , 80 ]. Besides, these flexible frameworks can easily adjust their configurations to adapt to the analyte molecules.…”

This review summarizes the recent advances concerning metal–organic frameworks (MOFs) modified with several biomolecules (e.g., amino acids, nucleobases, proteins, antibodies, aptamers, etc.) as ligands to prepare affinity-based sorbents for application in the sample preparation field. The preparation and incorporation strategies of these MOF-based affinity materials were described. Additionally, the different types of ligands that can be employed for the synthesis of these biocomposites and their application as sorbents for the selective extraction of molecules and clean-up of complex real samples is reported. The most important features of the developed biocomposites will be discussed throughout the text in different sections, and several examples will be also commented on in detail.

“…At 298 K and 253 K, the carbon dioxide adsorption capacity for 1-Ph was more than 23% and 50% higher than that for UMCM-1-NH 2 . Alqadami et al [104] adopted PSM to obtain a mesoporous amide citric anhydride MOF (denoted as AMCA-MIL-53(Al)) by covalent bond modification among citric acid anhydride (CA), amino (-NH 2 ), and NH 2 -MIL-53(A1). At 318 K, the maximum adsorption capacity of the divalent-led ion in a single layer was up to 390 mg/g.…”

Technology for the Remediation of Water Pollution: A Review on the Fabrication of Metal Organic Frameworks

The ineffective control of the release of pollutants into water has led to serious water pollution. Compared with conditions in the past, the polluting components in aquatic environments have become increasingly complex. Some emerging substances have led to a new threat to the safety of water. Therefore, developing cost-effective technologies for the remediation of water pollution is urgently needed. Adsorption has been considered the most effective operational unit in water treatment processes and thus adsorption materials have gained wide attention. Among them, metal organic frameworks (denoted as MOFs) have been rapidly developed in recent years due to their unique physicochemical performance. They are characterized by larger porosity and larger specific surface area, easier pore structure designing, and comfortable structural modification. In many fields such as adsorption, separation, storage, and transportation, MOFs show a better performance than conventional adsorption materials such as active carbon. Their performance is often dependent on their structural distribution. To optimize the use of MOFs, their fabrication should be given more attention, without being limited to conventional preparation methods. Alternative preparation methods are given in this review, such as diffusion, solvent thermal, microwave, and ion thermal synthesis. Furthermore, developing functionalized MOFs is an available option to improve the removal efficiencies of a specific contaminant through pre-synthetic modification and post-synthesis modification. Post-synthesis modification has become a recent research hotspot. The coupling of MOFs with other techniques would be another option to ameliorate the remediation of water pollution. On one hand, their intrinsic drawbacks may be reduced. On the other hand, their performance may be enhanced due to their interaction behaviors. Overall, such coupling technologies are able to enhance the performance of an individual material. Because the excellent performance of MOF materials has been widely recognized and their developments have received wide attention, especially in environmental fields, in the present work we provide a review of fabrication of MOFs so as to motivate readers to deepen their understanding of the use of MOFs.
