“…[ 42 ] However, MOF‐based MMMs have mainly focused on industrially relevant gas separation applications, [ 43–49 ] and their application for water remediation has been barely explored. [ 50–52 ] This includes removal of organic dyes, [ 53 ] arsenate, [ 54 ] humic acid, [ 55 ] for antifouling properties, [ 56 ] or simply to increase flux while rejecting impurities. [ 57 ] To the best of our knowledge, no MOF‐based MMMs have been reported for the removal of mercury species from water.…”

The mercury removal efficiency of a novel metal‐organic framework (MOF) derived from the amino acid S‐methyl‐L‐cysteine is presented and the process is characterized by single‐crystal X‐ray crystallography. A feasibility study is further presented on the performance of this MOF—and also that of another MOF derived from the amino acid L‐methionine—when used as the sorbent in mixed matrix membranes (MMMs). These MOF‐based MMMs exhibit high efficiency and selectivity—in both static and dynamic regimes—in the removal of Hg2+ from aqueous environments, due to the high density of thioalkyl groups decorating MOF channels. Both MMMs are capable to reduce different concentration of the pollutant to acceptable limits for drinking water (<2 parts per billion). In addition, a novel device, consisting of the recirculation and adsorption of contaminated solutions through the MOF–MMMs, is designed and successfully explored in the selective capture of Hg2+. Thus, filtration of Hg2+ solutions with multiple passes through the permeation cell shows a gradual decrease of the pollutant concentration. These results suggest that MOF‐based MMMs can be implemented in water remediation, helping to reduce either contaminants from accidental unauthorized or deliberate metal industrial dumping and to ensure access for clean and potable freshwater.

“…[ 29 ] Compared with the diffraction peaks of the simulated MOF‐199, the broadening of the reflection for the synthesized MOF‐199 was due to the smaller crystallite size. [ 30 ] Meanwhile, due to the pore‐filling effects [ 31 ] and different orientations of the crystals, [ 32 ] the XRD intensity of the first two peaks was lower than the simulated one. The FT‐IR spectrum of the synthesized MOF‐199 is illustrated in Figure S1.…”

MOF-199@PVDF composite membranes are prepared by blending with different amounts of ultrasonic synthesized MOF-199 nanomaterials for improving the pure water flux (PWF) and achieving better antifouling and antibacterial performance. The membrane morphology, elemental composition, and surface properties are analyzed by various means of characterizations, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, and water contact angle measurements. The performance of the modified membranes is also determined from the perspective of the PWF, bovine serum albumin rejection, as well as antifouling and antibacterial properties. Due to the variation in the viscosity of dope solution, the composite membranes possess remarkably different morphology, and the M5 membrane, which exhibited a sponge-like structure, the largest surface pore size, and the highest porosity, shows the highest PWF, reaching up to 185.05 L/m 2 h. Moreover, with the incorporation of MOF-199 nanocrystals, the antifouling property, together with the antibacterial property, toward both gram-negative bacteria and gram-positive bacteria, based on M5 and M7 membranes, increases dramatically compared with the pristine polyvinylidene fluoride membrane. In addition, the long-term permeation performance and copper leakage of the membrane are investigated. As a result, the composite membrane, M5, shows great potential in real water treatment.

“…Polymer precipitation occurs because of the solvent and nonsolvent exchange. , The exchange continues until demixing takes place in such a way that the initial homogeneous blending turns into two phases: the polymer-rich phase with embedded MOF particles that gives rise to the membrane structure and the liquid-rich phase that forms the pores. , The internal structure of the final membranes is asymmetric with a dense skin layer and finger-type pores. Several MOFs including ZIF-8, ZIF-L, MIL-53(Al), MIL-68(Al), HKUST-1, , HKUST-1@GO, Cu(tpa)@GO, UiO-NH 2 , UiO-66@GO, MOF-5, Ag-MOF, Ce-MOF, Zn/Co-MOF-74, TMU-5, etc. have been used for functionalization of polymeric membranes for water and wastewater treatment applications.…”

Metal organic frameworks (MOFs) represent one of the largest classes of porous crystalline materials. MOFs have been increasingly applied as functionalizing agents for membranes because of their porosity, high surface area, small particle size, aspect ratio control, tuneability, compatibility with a polymeric network, and exuberance of diverse functional groups. In this comprehensive review paper, we discuss achievements, opportunities, and challenges related to the functionalization of different types of membranes using MOFs for water and wastewater treatment and desalination. The current synthesis and fabrication approaches of MOF-functionalized membranes were identified and critically reviewed. The effects of MOFs on membrane performance, including permeation, selectivity, and antifouling, were discussed. Also, the application of MOF-functionalized membranes in aqueous environments for conventional applications such as heavy metal removal and emerging applications such as resource recovery was enunciated. Finally, recommendations and future directions were provided for further improvement in the field of MOF-functionalized membranes for water treatment and reuse.
